With the release of the first beta for iOS 7, many are flocking to third-party UDID activation websites, but for no real reason. Avoid that altogether by following this guide.
It turns out that a simple update will allow iOS to skip the UDID check. There’s no telling if this will work on future versions of the iOS 7 beta, so only time will tell.
Basically, all you have to do is to restore to iOS 6.1.4, and then update to the iOS 7 beta 1 IPSW file. You can find the iOS 6.1.4 IPSW links here, and the iOS 7 beta 1 links here.
I’ve confirmed three times that this method works, whereas the normal restore to iOS 7 brings up a message saying how my device was not a part of the iOS developer program.
