FAQ: What T-Mobile's New G1 Phone Will Do For You

The T-Mobile G1 features an iPhone-like touchscreen that lets you swipe across to navigate through menus and long-press to open options or drag-and-drop files. It also has a pull-out QWERTY keyboard and a navigation trackball.

The G1 comes with integrated Amazon MP3 functionality, letting you surf through the site's music store and do one-click ordering. Its default music player has options to search for related material on services such as Google or YouTube while a song is playing. Of course, a third-party app could ultimately replace that player if you so chose.

This first Android phone has Google Talk built into the platform and also supports AOL, Yahoo Messenger, and Windows Live Messenger.

The team indicates the G1 will not have tethering functionality as of now.

The Android platform supports Word and Excel documents, but does not offer Exchange integration (enterprise e-mail). The Google team, however, indicated that third-party developers will likely create applications for these purposes in the near future.

Android's default browser is an open-source browser ( WebKit) based on the same foundation as Chrome, though it is not branded as such. Engineers describe it as a Chrome-like program that's optimized for the small screen.
