I have an iphone 2G on firmware 2.1. AND I know, I just learned this app is for 3.0 firmware I downloaded ActivateMMS2G from Cydia and it bricked my iphone. Now I'm stuck on the apple logo boot screen. My iphone won't connect to my computer or anything. So what should I do to unbrick my iphone?????? I would really prefer to not have to restore!
