I think I just unlocked my Vibrant, using instructions from here: Captivate & Vibrant Unlock Instructions However, how do I know for sure? I installed an AT&T sim card, and get this screen: I did not get any popup, the phone didn't ask for any code. Does that mean it's unlocked? Sorry for the stupid question, but I have no idea what the stock behavior is so I don't know what is normal and what's changed. Thanks!!
