i sadly have t-mobile and the past 3 phones i've gotten from them, all different brands even, have been returned multiple times for problems which, in each and every instance, they've never heard of customers having! the sidekick was returned twice before i got a music express, which was returned 3 times before i upgraded to a gravity, which is on it's 3rd return as well. they have no "lemon law" and won't give me a different phone, it has to be the same one unless i buy a new phone. it sucks...i've never had such unreliable phones!
