Hi, I have an i phone and it has been set back to the factory setting which means i can only get emergeny phone calls, NOTHING ELSE.

I have purchased and down loaded ILiberty which jailbreaks and unlocks the phone, i have also uninstalled the new version of I Tunes and reintalled the 1.1.4 version,.
The problem i am having is once i have conected the phone to mt L-Top i tunes goes through all the set up, but at the end it comes up with THE I PHONE CANNOT BE USED WITH I TUNES BECAUSE THE INFORMATION REQUIRED FOR ACTIVATION COULD NOT BE OBTAINED FROM THE I PHONE....... i am well lost...
