Unable to activate my restored iphone?

My dad gave me his old iPhone 4 after restoring it to its factory settings.
It comes up with an error message that states

"Unable to complete your activation
This device is not registered as part of the iPhone Developer Program.
If you are a member of the program, please register your device in the iPhone Developer Program Portal."

I've tried wiping the phone again and putting it in recovery mode.
Also tried following the link to the developer portal thing but that didn't help, whether or not I did it right.

Any help?

Try using another computer and using the latest version of itunes… Be sure yoi have internet connection while performing such task since it needs to be verified by apple for a restore.

hope it helps

It might be the incorrect model for the provider you are trying to put into service with.

  • Unable to make calls on Iphone 4 I've never had a problem with my iPhone 4 until a few days ago. Whenever I make a phone call all i hear is a crackling noise… Sometimes I won't hear anything at all. No ringing sound, no static noise, nothing. I have no idea why this happened but i'm unable to make/receive phone calls. I also made this youtube video to show you what is going on: +Also, the speakers work. Other than this problem the iphone is in perfect condition.
