The LG Quantum is a quad-band world phone with a speakerphone, call waiting, call forwarding, conference calling, voice dialing, simultaneous voice and data, and text and multimedia messaging. The Quantum is 3G-capable and has Wi-Fi (802.11b/g/n), Bluetooth 2.1, and GPS. Unfortunately, Windows Phone 7 doesn't currently support tethering.
Like the Focus and Surround, the Quantum comes preloaded with a number of AT&T services, including AT&T Navigator, AT&T Radio, and AT&T U-verse Mobile, which allows you to download TV shows via Wi-Fi onto the phone. For a limited time, AT&T is offering customers who purchase a Windows Phone 7 device a free Entertainment Pack, which includes a 30-day trial to U-Verse Mobile (normally $9.99 per month), a 30-day Zune Pass, and the Ilomilo Xbox Live Arcade game.
LG also throws in 10 free apps, including Look n Type, Workout Tracker, Panorama Shot, a Scan Search augmented reality app, and Tool Box (features a unit converter and flashlight), through its dedicated channel within the Windows Phone Marketplace. With apps costing anywhere from $1.99 up to $6.99, the free titles are certainly appreciated. LG said that it will continue to release free apps on a regular basis exclusively to its customers for a limited time.
As you're downloading apps--as well as song, videos, and games--keep in mind that the LG Quantum has 16GB of internal memory with no option for expandable memory. One tip for freeing up storage while still being able to enjoy tunes is to stream music from services, such as Zune Pass, Slacker, and I Heart Radio, or use the Zune's built-in radio. Also, unlike other platforms, you can actually uninstall the preloaded AT&T apps if you're not going to use them. The services will only reinstall the programs if you happen to perform a hard reset on the device.
Finally, the LG Quantum offers a 5-megapixel camera with an LED flash, 5x zoom, and 720p HD video capture. There are multiple editing options, including various shooting modes (or Intelligent Shot as LG calls them), brightness and white-balance settings, color effects, and antishake.
The picture quality on indoor shots was a bit subpar. Colors looked dull, and there was also some graininess to the images. However, photos taken outdoors were more vibrant. Video quality was quite good. The picture was clear without any sign of the haziness or halo effect that often plagues other camera phones. Though Windows Phone 7 doesn't offer an easy way to upload videos to YouTube or your social networks, the LG Quantum supports DLNA technology so you can wirelessly stream content from your phone to a compatible device using the Play To feature on the handset.
We tested the quad-band (GSM 850/900/1800/1900) LG Quantum in New York and Washington, D.C., and call quality was good. On our side, the audio was mostly clear with some slight background noise. There was no voice distortion, though sound quality could have been slightly richer. Minor quibbles aside, we were quite satisfied with the voice performance, and friends also reported good results on their end.

Speakerphone quality was also decent. Volume was just a touch soft, even at its highest level, for holding conversations in noisier environments, but the audio was clear and not too hollow. Meanwhile, friends said they couldn't even tell we were on speakerphone. We had no problems pairing the Quantum with the Logitech Mobile Traveller Bluetooth headset or the Motorola S9 Bluetooth Active Headphones.
AT&T's network provided reliable 3G coverage in Manhattan and the metropolitan D.C. area, with decent speeds. CNET"s full site loaded in 30 seconds, and the mobile sites for CNN and ESPN came up in 10 seconds and 11 seconds, respectively. YouTube videos took several seconds to load, but it played back without interruption and with synchronized audio and picture.
Powered by a 1GHz Snapdragon processor, the Quantum performed smoothly throughout our review period. Apps launched almost immediately, and if there were delays, they were minimal. We were able to play games and watch video without any problems.
The LG Quantum ships with a 1,500mAh lithium ion battery with a rated talk time 6 hours and up to 14.6 days of standby time. In our battery drain tests, the Quantum provided 6.25 hours of continuous talk time on a single charge. According to FCC radiation tests, the Quantum has a digital SAR rating of 0.35 W/kg.
