The dual-band CDMA/EV-DO Centro measures 4.2 x 2.1 x 0.7 inches and weighs 4.2 ounces. While this isn't that much smaller than a typical Treo, Centro feels much better in the hand. That's mostly because it sports more of capsule shape and a rounded ...

I did notice that AT&T maintained a signal more strongly and for a longer period than my T-Mobile BlackBerry did. Places where I had only GPRS with T-Mobile I had EDGE with AT&T

Of course, if you already have a portable XM receiver this feature doesn't really offer much

The $450 (when purchased direct from Nokia - no carrier offers it as of this writing) E65is a quad-band GSM slider-style phone which measures a compact 4.1 x 1.9 x .6 inches and tips the scales at a tick over 4 ounces.

The N95 slider's 240 x 320 display is fairly large measuring 2.6 inches diagonally, and it has an adjacent sensor to adjust brightness based on ambient lighting conditions

That same 3.5 mm jack also supports TV out via an included composite video cable. We had to change the default output from PAL to NTSC before the feature would work properly, and display quality is mediocre at best when viewed on a big screen, but it ...

There's a lot to like about the N76, if not $500 worth. For starters, it's an attractive, sturdy clamshell with two displays: an external (1.4-inch, 160 x 128 pixels, 262,000 color TFT LCD) with handy music playback buttons underneath, and an internal ...

The N76 can also check e-mail and surf the Internet, but not all that quickly. The phone lacks 3G support, so you're stuck browsing at EDGE speeds. It's handy to have for a quick look-up, but that also is for emergency use only

The Sprint Mogul in brushed silver weighs in at 6.5 ounces and measures 4.3 x 2.3 x 0.7 inches, which makes it just a sliver heavier and taller than its predecessor, the PPC-6700, and just slightly thinner. It also takes the important step of making ...

We also groused about the Pearl's lack of stereo headphones and the use of a mini-stereo jack that wouldn't take standard headphones. RIM fixed that in the Curve as well, shipping it with a hands-free headset that includes stereo earbuds and that ...

As a phone, the Curve sounded very good. (I tested it on the Rogers Wireless network in Canada.) RIM says this is partly thanks to superior noise cancellation technology. Like the Pearl and other recent BlackBerries, it also includes a surprisingly ...

The dual-mode CDMA/GSM smartphone gives users the freedom to make calls, send messages, and receive e-mails worldwide. It also offers EV-DO support, multimedia capabilities, and impressive performance.

With the phone can access voice in 157 countries, including 135 via GSM, which means that users will have the opportunity to say "Can you hear me now?" in dozens of languages. E-mail coverage is available in roughly 60 countries. Depending on your ...

The 800/1900 MHz CDMA 755p runs Palm OS 5.4.9 (Garnet) and is kin to the GSM Treo 680 (and Windows-based 750) available through AT&T. Basic hardware specs are similar to the outgoing 700pthe 755p sports the same 312 MHz Intel XScale CPU, 128 MB of ...

Ultimately, the 755p isn't the great leap forward many Palm devotees are waiting for because it doesn't deliver any earth-shattering new features over it's predecessor. Nevertheless, while the 755p probably won't compel many upgrades from the 700p, it ...

Not only does the P4000's Windows Mobile operating system, like the BlackBerry, enable push e-mail, it also features a full QWERTY keyboard - which slides out from under the 2.8-inch touch-sensitive screen - and a scroll wheel that you push in, ...

Its physical interface is fairly well thought out. The front surface is mostly taken up with the screen, but at the top, there are dedicated buttons for launching the mail and browser applications. Below the screen, there's a circular four-way ...
