I heard there would be an early upgrade fee? like $100 more for each model , I'm fine with paying $299 for a 16GB or $399 for a 32GB
I think everyone that isn't eligable should qualify for the $100 more expensive early upgrade. It just depends on how Apple wants AT&T to handle it.
Actually the "early" upgrade pricing is $200 more than the new/upgrade eligible customer. There's a chance AT&T will do this again, then again, there's a chance they won't. As others have said, LOG IN TO YOUR AT&T ACCOUNT and verify when AT&T says you are eligible to upgrade.
