Fix for incorrect data plan after upgrade on Att?
If you don't have the correct data plan and want to upgrade without having your iPhone data disabled what do you do?
I upgraded received a notice on the iphone that I dont have a iphone data plan (my sim is swapped with my blackberry). I restored the iphone yesterday and used a friends sim for the activation and the swapped my blackberry sim that I was using before the 3.0 upgrade. It was working just like it did before the upgrade. Until today! the message is back.
Hoe can I over come this without getting a sim for the iphone?
