I recently had to reformat my PC and lost everything. I reinstalled iTunes and now it says my iPhone is sync'd with another PC.
I know where to find my ID KEY within my PC/iTune settings, but where can I find the ID Library KEY within my iPhone (using WinSCP), I have search various library folders etc. but dont seem to be able to find it. - It must be somwhere...
Basically I don't want to loose everything from my iPhone and wanted to change the ID KEY to that of my PC.
The same thing happened with me. what i did was i authorized the computer again disconnected the phone and plugged it back and clicked on the transfer purchases from iphone button. it worked!
