Hi all. I have a question about the X10 on the ATT network. I just got my X10 and can only get the Edge network on it. No matter what I do I can't get 3G. I've tried my buddies ATT sim card and it does the same thing. I also tried another friends of mine who is on Tmobile and it does get 3G on Tmobile. Everywhere I've read says that the X10 should work on the ATT 3G network. Is there something I need to set to get 3G?
