Got a question, I dialed *2 to talk to sprint about my bill and before it connected me it told me that there was an update available for my phone. It made me wait for about a minute or two, then it said the update was complete and it continued my call. After I talked to sprint I went to hang up and saw that it said that it was still updating just as I ended the call and then it said update failed or something like that. Anyone know what this update is for? Is sprint somehow able to tell that my phone is unlocked and has a custom rom on it and now my TEP insurance is void?
