Restored from iOS 7 BETA to iOS 6.1.3 and can't activate phone
The activation servers were overwhelmed presumably by the volume of activity on launch day. Now activation fails for a different reason - Apple is no longer signing iOS 6 software during the restore process.


Where can I find information about past versions of iOS and code-signing windows?


Once you get your OS activated either through iTunes or over the air, you will be able to load your backup as you had planned.

Apple would surely make it easier on a segment of its customer base if the service status page were kept updated thusly….
