Hey guys, I've followed the steps for redsn0w stuff and the jailbreak worked well, but I can't seem to unlock the phone. I'm trying to have it work on Tmobile and it won't recognize my sim card at all. I'm using a 16gb 3G iphone on version 3.0.1. No matter how many times I've tried, it just keeps telling me that there wasn't any sim installed. What can I do to fix this? As of now, this phone is just a glorified iTouch and I want to start using it!
