Got the device yesterday. So far, no problems at all. Works about the same as my carrier variant of the phone and No T-Mobile carrier apps. I am really pissed that T-Mobile essentially forced an app on me and a lot of other users that ruined the battery life of my old device and couldn't be removed. Now that's not an issue. I think in the future I will purchase unlocked phones. Much less hassle as long as you get the right one.
