Q: Activation error

You have a beta version of iOS 7 which expired on Saturday. They all did, all over the world. I'll give you the benefit of the doubt and assume that you are a developer with a legitimate copy of the beta. So just go to the Developer's forum, where you will find detailed instructions.

If you have a stolen, pirated version of iOS 7 beta you will have to go the somewhere other than an Apple support forum for help.

1) Download the current ipsw
2) turn off iPhone
3) Hold home button and connect USB cable (connected to computer), until the itunes screen on mobile
4) Holding command or option (can not remember, lol), click restore
5) Select the ipsw downloaded
6) Be happy =]
