The cat and mouse game continues between Apple and the Dev Team, a group of guys who are passionate about freeing Apple handheld devices from the company's short leash. The Dev Team has been jailbreaking new Apple firmware for years, and it just did so again--though this time around it seems Apple is still taking the decisive lead.

The team announced Friday the availability of PwnageTool 3.13, which allows for jailbreaking and unlocking the iPhone 3GS running the latest firmware, version 3.1. Currently only a Mac version of the tool is available, but the Windows version will be out soon. (Keep in mind, however, that you download and use the PwnageTool at your own risk.)

The tool creates a custom firmware from the version 3.1 firmware released by Apple. To install it, you put the phone into recovery mode (turn it off, then plug it in while holding down the Home button) and use iTunes to restore the phone with the custom firmware (hold down the Option key while clicking on the Restore button).

The custom firmware, apart from jailbreaking, will not upgrade the baseband--the chip that connects the phone to a service provider--and therefore still allows the phone to be unlocked.

But there's a catch here. The tool only works with the iPhone 3GS that has been jailbroken with the firmware version 3.0 or 3.0.1. This means if you buy a new iPhone 3GS that already has version 3.1 on it or you have updated to version 3.1 using iTunes, there's still no way to have your phone jailbroken. There's even a rumor that there might never be one, unless a new exploit is found.

If this is true, it seems Apple has finally been able to gain significant ground in stopping the practice it claims could pose a threat to national security. And for thousands, if not millions of iPhone 3GS users who rely on jailbreaking and unlocking to use their phones with the service of their choice, this is sad news.

The Gorillamobile securely attaches the iPhone to a cycle's driving bar.

Are you an avid cyclist who wants to use the iPhone as your GPS navigator? Joby has something for you.

The maker of the recently introduced Gorillatorch announced Thursday its newest iteration of something that can stay really well on something else: the Gorillamobile for the iPhone 3G(S).

This is basically a tripod docking station for the phone which, apart from keeping the phone on any surfaces, can help securely attach the phone to object of different shapes, such as the driving bar of a bicycle.

The key to making the tripod work the way Joby claims it does is the ball-and-socket construction that allows for fully articulated movement of the flexible, wrappable legs.

The accessory comes with four interchangeable quick-release adapters for the iPhone 3G, 3GS, and other mobile devices. It also has a custom-engineered, slim-line iPhone case.

In addition to the flexible tripod and iPhone case, the Gorillamobile for 3G/3GS package also includes two removable 3M adhesive clips and a universal camera adapter. This means apart that from the iPhones, the accessory can also be used with other mobile devices, such as mobile game consoles or video players, when you need to keep your hands free for other things.

Though the Gorillamobile weighs just 4.5 ounces and is only 8 inches tall, it carries a rather hefty price tag of around $40. It's available for purchase now.

I got the Jesus phone and a Platinum Plus card. Isn't that enough street cred for you?

I'm not a fan of protective case for gadgets (which, as long as they function, are fine the way they are, even with a few scratches). For this reason, the only things I've put on my iPhone 3GS so far, and only when I travel, are the Mophie Juice packs, which add more battery life to the phone.

I just, however, found a new protective case that I actually am going to use more regularly, for the sake of convenience. It's the Case-Mate I.D. case.

Unlike other protective cases that try to be as slim as possible, the I.D. case deliberately bulks out at the phone's back to create a small pouch that's just large enough to fit two credit cards or, in my case, my driver's license and a library card (yes, I read).

Of course, you can swap these out for any two cards you want. The point is this is very convenient, especially when the iPhone is something a lot of us don't want to be separated from. And I would like to stress the inseparable notion, as you definitely don't want to lose the phone and the two important cards attached to it.

Despite the added functionality, the case actually only adds another 2.5 mm (about one-tenth of an inch) of thickness to the phone, compared with other purely protective cases.

Other than that, the Case-Mate I.D. is very much like most protective cases. It comes with an easily attached protective film for the phone's screen and another protective layer for the back of the phone (so the card won't mess up all the fingerprints you've gathered).

The Case-Mate I.D. works with both the iPhone 3G and 3GS. It comes in eight colors and costs $30, which is a little more expensive than other cases that add no extra usability to the phone.

So far I've tested four flat-fee GPS applications for the iPhone with built-in offline maps: Navigon, iGo My Way, TomTom, and CoPilot Live. They all have pros and cons, but they share a few common shortcomings: a lack of real-time traffic, no support for text-to-speech (except for Navigon with its recent update), and outdated maps.

AT&T Navigator's real-time traffic works well most of the time, even where 3G signal is not available.

I've just finished testing a GPS navigation app that offers all of those previously unavailable features: the AT&T Navigator (version 1.2i.5). The catch? It doesn't have built-in maps (meaning you will need a working data connection to download the maps in real time) and it requires a monthly subscription of $10. The app itself is free.

This is one of the first GPS navigation applications made for the iPhone. It's actually a product by TeleNav and is also available for other cell carriers, including Sprint and Alltel.

Unlike the other aforementioned apps that take an hour or so to download using Wi-Fi, the AT&T Navigator has no built-in maps and therefore is a snap to install on the iPhone, even via a 3G or Edge connection. This makes it a perfect quick add-on when you suddenly need a GPS navigator.

The app also launches very quickly, taking just a second or two on my iPhone 3GS. When it can (more on this later), it also picks up GPS signals very fast. After about a week of use, I can say I really like the real-time traffic updates--which warn you both onscreen and audibly--and the text-to-speech features. This is especially helpful when you are in a unfamiliar town.

However, I found out that the traffic updates are available mostly for freeways only, unlike Google Maps, which offer them all the way down to street level for major cities.

Since I got my iPhone 3GS a couple of months ago, I've been wondering when I would really benefit from its highly anticipated faster 3G capability. I finally got the answer, and as it turns out, the wait is far from over.

AT&T announced Wednesday details of its rollout plans for High Speed Packet Access (HSPA) 7.2 3G technology. This is the next generation of 3G, and it offers up to 7.2Mbps data connection speeds (as opposed to the 2Mbps and 3.6Mbps of the current 3G).

(This is, of course, just the theoretical number. Typical real-world downlink and uplink speeds will likely be less than that depending on location, device, and overall traffic on the local wireless network at a given time. Nonetheless, this promises a significant boost. HSPA 7.2 is part of the 3rd Generation Partnership Project (3GPP) family of technologies, which include GSM, UMTS, and the Emerging LTE technology. HSPA 7.2 offers backward-compatibility, meaning it also works with existing 3G and 2G devices at the lower device-specific speed.)

According to the announcement, the new speed will be available by the end of the year. Unfortunately, it's available only in six cities in the U.S., including Charlotte, N.C.; Chicago; Dallas; Houston; Los Angeles; and Miami. This means the rest of the country, including the San Francisco Bay Area where I am, must continue to wait.

It's unclear how long the wait will be for the rest of the cities, but the company says it plans to deploy HSPA 7.2 in 25 of the nation's 30 largest markets by the end of 2010, and to reach about 90 percent of its existing 3G network footprint with HSPA 7.2 by the end of 2011.

While this is rather sad news for me, for most people it won't mean much, as chances are your phone is not compatible with the higher 3G speed. Currently, the iPhone 3GS is the only HSPA 7.2-ready smartphone I know that AT&T offers.

However, AT&T assures that it will offer more compatible devices with the rollout of HSPA 7.2. The company expects to have six HSPA 7.2-compatible smartphones in its device portfolio by the end of the year, as well as two new LaptopConnect cards.

The rollout of HSPA 7.2 is part of AT&T's plan to invest some $18 billion this year, of which more than two-thirds is going toward broadband and wireless. Key projects of this investment include, in AT&T's words:

CoPilot Live's map view could use some cleanup and suffers some lag when switching between the vertical and horizontal positions.

CoPilot Live is the fourth turn-by-turn GPS application with offline built-in maps for all of North America that I have on my iPhone 3GS. After Navigon, iGo My Way, and TomTom, I thought there would be nothing new I could find in a navigation app. I was wrong.

CoPilot Live offers a quick way to switch between modes of travel, which include auto, RV, motorcycle, biking, and walking. This makes the app ideal for getting around town, especially, say, if you need to change from driving a car to walking. The Navigon app offers a similar option, but you have to dig pretty deep into the menu to change your travel mode. With CoPilot you can do this anytime, even in the middle of an existing route, just via a few taps.

Another nice thing about CoPilot is the Live Services option, which includes Live Weather and Live Link. Live Weather lets you see local weather or weather in a different city. Live Link connects CoPilot Live users, allowing them to send messages or share locations. I wasn't able to try this out as I was the only one I know who used the app during the testing.

The Live Services option, of course, requires an Internet connection and is only available when there's a cellular or Wi-Fi signal. Unfortunately, the most anticipated feature that also requires an Internet connection, the real-time traffic option, is not yet available, though there's a placeholder for it within the Live Services section of the app. According to ALK Technologies, maker of the CoPilot Live, this service will be added via an update that's coming out by the end of the month and costs another $20 per year, on top of the current $35 flat fee for the app. No other flat-free iPhone GPS apps with offline maps currently offer real-time traffic.

Also missing is the text-to-speech feature, where the app would read out the name of the street. Nonetheless, the app has a wide selection of voices for you to choose from. It includes voices of 29 languages, each with a few options of accents, both male and female. It's probably the most versatile GPS app for the iPhone in terms of languages it supports.

If you need a GPS device to get around, it's becoming more likely you'll get yourself a mobile phone with built-in satellite mapping than buy a standalone personal navigation device.

According to market research firm iSuppli, by 2011, virtually all smartphones will sport built-in GPS functionality, and by 2014 there might be no more market left for PNDs.

The Palm Pre is one smartphone that offers viable GPS navigation solutions.

While this is a grand statement, it's quite credible. Just a year or two ago, it was hard to find a phone with built-in GPS functionality that actually worked reliably. Now look at my iPhone 3GS. I have all three major GPS applications on it, including TomTom, Navigon, and iGo My Way, and each can turn the phone into a dependable navigator. In addition, I am now testing the fourth one, CoPilot Live from ALK Technologies.

While I may be unusual--mostly because nobody needs more than one GPS app on his or her phone--the truth is that more and more phones offer the same feature and more people are using their phones as their primary GPS navigator while driving.

The Palm Pre, for example, also offers a great GPS navigator provided by TelNav, and my co-worker Joseph Kaminiski sure has made good use of it. Prior to the Pre, Joseph used the Treo 800 for the same purpose.

Nonetheless, for now, the market for PNDs is still going strong. According to iSuppli, PNDs will continue to lead the navigation market in 2009, with some 114 million sets predicted to be in use by the end of the year, compared with 57.8 million navigation-enabled smart phones.

New smartphone models are becoming increasingly suitable for use as navigators due to their larger displays, bigger internal storage, faster processors, and most importantly, the increased number of developers creating apps for them. As a matter of fact, all current navigation solutions on smartphones are applications developed by third parties.

iSuppli predicted that thanks to such factors, the number of people who use the iPhone alone as a navigator will increase from just 2 million in 2009 to 20 million by 2013.

Personally, however, I still believe there will be a market left for personal navigation devices. Though I have been making good use of my phone for getting me places, I still like a standalone GPS device for my car as sometimes while driving, my iPhone needs to be used as what it's designed to be: a phone.

TomTom has a very easy-to-use menu with large buttons.

TomTom U.S. & Canada is the third full-feature turn-by-turn flat-fee navigation app with built-in maps in the App Store that covers the entire U.S. and Canada.

Like the first two apps, Navigon and iGo My Way, the TomTom app will turn your iPhone 3G or 3GS into a decently dependable driving navigator. However, like the other two, it's far from perfect.

The TomTom app took about 6 seconds to load on my iPhone 3GS, which is very fast (the other two apps took about 15 seconds), and displayed a very easy-to-use interface with big buttons. It also offers a quick and convenient way to enter an address or to find a point of interest (POI) from its very large database of POIs.

The map view of the TomTom is rather messy and much less beautiful- and clean-looking than that of the Navigon or the iGo My Way apps.

(Credit: Screenshot by Dong Ngo/CNET)

After almost a week of use, I found that both the map and POI database are slightly outdated. It once couldn't find an address and twice showed me POIs that were no longer in business. During this recession, however, it's not exactly the app that's to blame.

Good news is, like the Navigon after its first update, you can tap on a POI to dial it up, and I would highly recommend doing this before you decide to go there, just to make sure that it's still in business.

Similar to the Navigon, the TomTom can also pull addresses from the phone's contacts, which is a very convenient feature. However, while the Navigon is very good at reading contacts' addresses, the TomTom is very picky. It seems to only understand addresses that have a zip code. Take the zip code out and it will ask you to enter the address manually. This means more than 60 percent or so of the addresses in my contacts won't work. This is sort of strange, as the app won't require a zip code when you type in addresses manually.

The TomTom took very little time (a few seconds) to pick up a GPS signal on my iPhone 3GS, and its navigation was accurate enough. Once in a while it would probably lead you to a location that's slightly off from the actual address, but that happens with every GPS navigator I've used.

Of the three apps, the TomTom has the largest selection of voices, including many languages from English to Danish, Thai, and Chinese. With English alone, you'll find 11 different accents, both male and female. Still, like the other two apps, it doesn't have text-to-speech where it can read you the name of the street that you're supposed to turn onto.

The TomTom's map view, unfortunately, is not as good-looking as that of the Navigon or the iGo My Way. ... Read more
