BlackBerry has also introduced the Curve 8520, now exclusive to T-Mobile, which offers a new feature that impresses critics: an optical trackpad instead of the trackball found on other BlackBerry smartphones. Reviewers predict that the trackpad will eventually replace the trackball on all BlackBerry models, and most find it easy to use once they get accustomed to it. The Curve 8250's biggest downside is its lack of 3G network support, which means slower data transfer speeds. Otherwise, T-Mobile's new Blackberry phone is somewhat similar to other models in the Curve series. Its currently free with a two-year contract.
Finally, T-Mobile's G1 (*Est. $100 with new contract), the "Google phone," recently got a firmware upgrade (Android 1.5) that adds a number of features, including video capture and stereo Bluetooth, making it a more palatable smartphone option.
