I dunno m8.Appsync installed ? Vital to get apps synced that are cracked ,add the h a c k u l o.us source in cydia
I give you this clue here to rather use iTools
instead of iTunes (wich is even a greater bitch then Paris hilton ! ) that i only use to backup and restore.
With itools you can do everything that itunes can do for you and even more .
Check it out, i bet you wont regret it.
It is free and by every user much apreciated including myself.
Next time try to follow my suggestions even if they are hard to understand due to the fact that iam not a native english speaking person .Never the less i know what iam talking about (ok ,most of the time XD) and you get your device sooner back into a usable state.
And what da fuck is going on here ,am i the only one who can help him here to solve these little issues he faces ?
Anyone who feels addressed by this , is meant .
