iPhone activation help

[flylice3793]

After updating the new 3.0 update, my iphone wants me to activate again but I already have an account for it at AT&T. What do I do?

plug it into itunes again. It usually does this after an upgrade in my experience. If your device is with a legitimate carrier (AT&T) it'll work

Activation means it just needs to validate that you have an AT&T sim in your iPhone.
