A while back i tried this How to Unlock Your Samsung Galaxy S3 & Note 2 (No Rooting) - xda-developers to unlock my phone. I wasn't sure it as successful at the time though b/c i didnt get the confirmation that it was unlocked. Recently i was in the TM store and asked about unlocking the phone and the rep said i needed to request my phone be unlocked thru TM, then TM forwards the request to samsung, samsung authorizing the request and TM sending me the code and directions but i couldnt get to step 2 (below). I installed both a unactivated and activated ATT card and each time the phone booted to my lock screen. I could not make a call using either of the ATT sim cards. When i inserted the same un-activated card into a TM employees locked S4 i was able to get to step 2. Then TM & i tried clearing the partition cache and both a hard and soft reset and nothing. @ this point TM explained that it "seems" that the phone was already unlocked but couldnt prove it. After 4 hours of missteps TM agreed to replace my phone. Is there a way to confirm my phone is unlocked
