Unable to complete activation - account not registered

I'm having the same issue. Was able to restore to the iOS 7 beta, but neither iTunes or the Phone itself will activate and have that same error. My dev account is brand new and I just added the UDID around 7:30pm Eastern.

Same problem here.. Entered UDID fine, installed ios7, and can't activate. same error.

Same here. This better get resolved quick.

Or what?

same issue! im hoping that it is just a matter of time before the UDID gets processed and then it will activate. Apple's servers are probably crazy swamped because of WWDC!

Same thing is happening to me. Guess we just need to hold tight!

Same problem here :/

For my own sake, since I am now unreachable. Making your developer's phones unusable at wwdc, because of a ****-up, isn't exactly very clever.

they arent unusable, you can simply restore from restore mode....

Have you done this? It says on the dev site, you can't downgrade.

you can put the iphone in DFU mode and restore to the latest public version

Installing a beta on your only phone is not exactly an Einstein moment.

In the past, this hasn't worked.. not sure if it's different now.

just restored back to 6.1.4
