I have it from Sprint and I'm on my 3rd replacement in a week and a half. I turned mine in because the alt key (dot) stopped working at all and the wifi wasn't working. Every replacement has been a refurb with a keyboard that has at least 2 keys so sticky that they are useless. 2 of them have also failed to recognize my memory card. I'd much rather have my old one back at this point, at least I knew it was only one broken key as opposed to a an assortment of both oversensitive and sticky.
