For those that don't know I bought my phone as soon as it went on sale on the 14th. I requested my unlock code the next day. Well 3 weeks later I'm still waiting for my unlock code (I got the automated email the next day saying my request was being processed for my unlock code). Well, I got to thinking today, Tmobile made no other changes at all to the phone so did they even bother to SIM lock it? I put a non Tmobile SIM in my phone and it never asked me for an unlock code I'm going to try to find someone with an active non Tmobile SIM card that will let me borrow their SIM to test it. Has anyone else tried it yet??
