RIM BlackBerry 7750 (Verizon Wireless) review: RIM BlackBerry 7750 (Verizon Wireless)

Review Sections

The RIM BlackBerry 7750's phone book can hold more than a thousand entries, but actual size is dependent on the available memory. Other features include text messaging, a calendar, a calculator, a task list, USB support, a memo pad, an alarm clock, a game (Jawbreaker), three-way calling, a vibrate mode, and 20 polyphonic ring tones.

Accessorize: The 7750 comes with a full goody bag.

Mobile access to your POP3 or IMAP4 e-mail is handled in a number of ways. If your company has BlackBerry Enterprise Server installed on its servers, your IT team can help you get started. If, like ours, your company doesn't, you can use the BlackBerry Web Client to have e-mail messages wirelessly forwarded to your 7750; alternately, and even more conveniently, you can use the included e-mail redirector to push e-mail from Microsoft Outlook directly to the device. You can open and view--but not edit--e-mail attachments.

The BlackBerry 7750 uses Microsoft's ActiveSync application to transfer PIM data between the device and your desktop. We had no problems synchronizing our contact and calendar information onto the 7750 with ActiveSync. Of course, BlackBerry's PIM applications aren't as elegant as the systems on PalmOne and Pocket PC devices. But as we mentioned earlier, BlackBerry devices are less about showing off than about getting the job done. If you choose Compose to create a new e-mail message from the home screen, the 7750 tries to autocomplete the To field based on the information in your address book. When you have multiple e-mail addresses for one contact, a dialog box pops up prompting you to choose the appropriate address.

The handset ships with a fairly standard WAP 2.0 wireless browser, which we used to check Web-based e-mail services such as Yahoo and MSN. While the browser was not necessarily pretty, we were able to check those accounts easily. To our disappointment, unlike the BlackBerry 7100t, the 7750 doesn't ship with any instant-messaging software. Of course, you can purchase versions of AIM and Yahoo Messenger from Handango for around $20.

Though it lacks an SD card expansion slot, the mobile boasts 14MB of internal flash memory and 2MB of SRAM. While this may not seem like much, remember that the 7750 isn't necessarily a multimedia device, so running out of memory shouldn't be an issue. On the downside, the 7750 lacks Bluetooth and a speakerphone. They would have been fantastic additions.

We tested the dual-band RIM BlackBerry 7750 (CDMA 800/1900) on Verizon's network in the San Francisco Bay Area. The smart phone worked like a charm. We never lost a signal, whether here in downtown San Francisco, riding the bus across the San Francisco Bay Bridge, or in more residential areas in the East Bay. As with other BlackBerry phones, we often lost the speaker's sweet spot on our ear and had to move the headset around to hear conversations. In addition, callers could tell that we were using a cell phone. Using the 7750's included earbud-style headset changed the experience dramatically. Not only was it easier to hear speakers, callers reported that they could hear us better, too.

The 7750's battery life was excellent. We managed 4 hours of talk time on a single charge, beating the rated time of 3.3 hours. For standby time, we met the promised time of eight days. According to the FCC, the 7750 has a digital SAR rating of 1.27 watts per kilogram.
