Need to unlock my sprint phone sprint was acquire by tmobile. My phone was paid for, just never unlocked tried to get them to unlock it for some unknown reason they cannot unlock since what they said they encounter an error which trying to unlock they advise to bring in to a tmobile store i showed that it was paid off but still running into an error while trying to unlock they advised get new phone I advised "no" I dont want a new phone since this working just fine.
So back to original request is there any other way to unlock this phone another than paying some strange websites or a person is there a secret way of doing this. TIA
