I recently bought a used iPhone 3G from someone I know and I would like to transfer the apps which are on it which my friend had previously bought... If I had bought the apps I would use the "Transfer Purchases" tool in iTunes to do this etc etc, but as the iPhone was bought from someone who I do not know well enough really to ask to give me their apple ID so I can authorize the account there is no way I can do this. Does anyone know of any software or even hidden files style trick that I can use get the .ipa files from the iPhone onto the PC so I can sync with the rest of my data back onto the phone? Any help would be appreciated!!
