T-Mobile isn't the first U.S. carrier to offer the Wi-Fi-equipped BlackBerry Pearl 8120 (AT&T Wireless launched its 8120 earlier this year), but its version has a decidedly consumer spin. Thanks to T-Mobile's innovative HotSpot@Home technology, this Pearl lets you make VoIP calls over Wi-Fi. The voice-over-Wi-Fi feature improves reception in locations where cell signals are weak--and in our tests, the technology worked very well.
Other impressive features include a sharp 2.0-megapixel camera, an excellent multimedia player, and RIM's SureType predictive text-entry system for typing on a 20-key keyboard. Both voice quality and talk-time battery life were excellent: In our battery tests, the T-Mobile 8120 was still going strong after 10 hours--the maximum length of time we test for.
