The Duo's battery is rated for 3 hours talk time and 10 days on standby, and those estimates seem to jibe with our experience; we got more than three days out of a charge with moderate usage. For what it's worth, getting the battery in and out is a ...

We found the Duo's call audio quality to be very good, and that includes the speakerphone which is quite clear and loud

Specifically, we're talking about the AT&T Tilt, a device penned by prolific smartphone manufacturer HTC, and whose signature feature is adjustable screen

Flanking the D-Pad beneath are dedicated Windows, Internet Explorer, and E-mail buttons, along with the obligatory call and soft keys. A jog dial on the upper left edge eases one-handed navigation when you don't want to remove the stylus from storage, ...

What's so appealing about the Q 9h? It's very thin - 11.8 mm to the Curve's 15.5 mm. The QWERTY keyboard features well-marked keys with a roughened surface that prevents fingers slipping off them - a problem with many PDA keyboards

As a phone, the Q 9h is one of the best I've tried, although it's always difficult to separate handset performance from network performance. Still, voice quality was consistently good and, always important, loud. The speaker phone was particularly ...

The N75 measures 3.7x 2.1 x 0.8-inches and weighs 4.5 ounces, so it feels weighty in the hand. It's a quad-band GSM worldphone offered solely by AT&T Wireless, with 3G UMTS available for data subscribers

Currently selling for $99 with two-year agreement and rebates, the Nokia N75 is a decent music phone for those who need something more solid than the latest ultra-thin model

We're not used to being wowed by T-Mobile phones, since the trendiest and flashiest models usually go to other carriers, but the Shadow is a beautifully designed creation.

Nokia hopes to have better luck with a follow-on product, the E61i, which in spite of the backwards-sounding nomenclature is actually derived from the same platform (the original E61) that spawned the less-capable E62.

The phone's front has been slightly redesigned, with more space given to the call start and stop buttons, and the size of the keys on the QWERTY keyboard increased slightly

The Moto Q 9m is outfitted for 3G EV-DO data service, which delivered songs and Web pages quickly in our testing. And its Bluetooth profiles include A2DP support for wireless stereo headsets

First, purchasing is truly on the go -provided you happen have access to a Wi-Fi hotspot. AT&T's maple syrup EDGE network isn't up to the task of downloading 5 MB songs and, frankly, Apple probably protected our sanity by not providing the EDGE option ...

Overall, the 8320 is the best BlackBerry for T-Mobile customers now available. The only thing missing is GPS, which can be found in AT&T 8820. The 8320 worked fine with a Bluetooth Global Sat GPS receiver, however
