I liked this phone pretty well until the 'shift' key stopped working. It started acting up a week before warranty ran out--unfortunately, I didn't click to that, and I waited to see if it would work itself out. It just got worse.I had run down T-Mobile in this review previously, as they were not much help in this situation, but I am not sure that's fair. If the phone's out of warranty, it's out of warranty, you know? I was just frustrated. I've been content w/T-Mobile overall, though this instance wasn't resolved satisfactorily.Pretty good software, OK phone service, subpar keypad design. I see they've changed the keys on the 7105--maybe they changed some things for the better. I do not recommend the 7100, however.
