"Your iPhone could not be activated because the activation server is temporarily unavailable." i tried it many times in DFU mode buy it not working .. i tried micro sim cards but it definitely not word :( please anyone can help me fix this problem

Did you just update or restore this phone?

I have same message. Just tried the update yesterday. Phone NOT jail broke and my SIM card has been init since I bought it. I need my phone and information ASAP. Is backed up on comp but can't get to without phone! During update my laptop shut off. Problem started after I started it back up to finish the process. Why would that make a diff? What to do now???? Help!

Melanie has a same problem as I.

I repeat there is no PORT BLOCKING, there is NO GS Secure Server blocking, NEVER JAILBROKEN, iTunes reinstalled FRESH deleted all backups.

so dont get as upset when there is NO SOLUTION.
