So i did my iphone frim 2.0.2 to 2.1 and everything worked like a charm.. I did my roommates phone on his own macbook and everything and it looked like it work but when it was done. It was saying connect to itunes and can only be used for emergency calls. But it shows T-mobile on as the carrier and it gets text messages. On the homepage wth is going on. I even tried to go back to 2.0.2 and it still does the same thing..
