There are 4 possible causes of this error:

• The activation server really IS unavailable. Rare, but it happens. Usually fixed within minutes.
• Your antivirus or firewall (or your router's firewall) is blocking access to the URL gs.apple.com on ports 80 and 443.
• Your phone is jailbroken.
• Your phone isn't jailbroken, but the computer you are connected to during the restore or update was used to hack or jailbreak some other iOS device, and its network database was corrupted in the process.

cannot activate but no error during activating but just blinking apple

Yes, because your iPhone is jailbroken as indicated in your other post.

My phone has not been jail broke. I plugged it in to ITunes simply to back it up , like Apple tells you to do, and it went into Restore mode and erased all of my info, then proceeded into the activiate mode. That was a week ago today and still after numerous calls to At&T and Apple then a trip to .my local AT&T,  I drove an hour and a half to the nearest Apple store and 3 hours later I walked out with a still locked up phone. Oh but they did offer to sell me a new one...NOT!!

what can i do if i have bought an i phone that was previously jail broken and i didnt know is there any way to fix the problem

okay thanks for the information and i didnt know anything about jailb but ill try downgrading from ios 6 and see if that fixes the problem

You can try a DFU Restore (google for it). Depending on how it was jailbroken this may resolve the problem by unjailbreaking it. However, if the hack included modifying the baseband this won't work. The other risk is that the phone was locked to a carrier. A DFU restore will re-lock it to the original carrier.

you are amazing its restoring factory settigs now i would of never figured it out

why when i restored my phone i get a message at the end says sim card doesn't support

It means that your phone is locked to a carrier, and the SIM card is not from the carrier the phone is locked to.

I restored my iPhone from ISO 4.1 to6.1.3but it doesn't work please help
