Jailbroken/Unlocked with Liberty+ but can't connect to itunes

[howie_ind]

I have iphone that was previously activated with AT&T through itunes. It firmware version is 1.1.4.

Yesterday I jailbroken/unlocked it using liberty+ through windows desktop. When I use another carrier SIM card, everything work fine but itune won't recognize iphone and displays error that iphone is damaged.

If I put back my AT&T SIM again and then itune recognizes my iphone.

Does anyone know how to fix this problem? I want to use itune to sync my music and other stuff from my desktop.

Thank you in advance for you help!!

Well,this is kinda funny (LOL),insert your AT&T sim,sync,then insert other sim.

Or try to restore through DFU mode,and then try other unlock method,I had the same problem,but not with AT&T sim....
