- Jake Ludington shares his first impressions of the T-Mobile myTouch 4G. The myTouch features HSPA+ 4G broadband service, both front and rear facing cameras, 720p video, Qik for lifecasting, and a number of other enhancements over 3G phones. In comparing speeds via Speedtest.net T-Mobile was at least twice as fast as Sprint 4G in side-by-side tests during this 48 hour period. myTouch also includes some features to track actions of your friends, as well lock the dialing and SMS features if small children are using your phone.
