I have already a working Iphone with v1.0.2 unlocked and working with non AT&T card.
After uploading a new theme over iPhoneHackToolkit1.0 the iphone is mising some Categories on Installer.
So my question is :
Can I restore it to 1.0.2 over iTunes?
Do I need to viriginize it?
Do I need to unlock also after restore?
