Hi. My friend upgraded my iPhone to 2.1 using his Mac. Unfortunately it is asking for his iTunes password when accessing the iStore on the phone. Is there an easy way to fix this? As I'm a PC user and iTunes doesn't work properly (Blue Screen Of Death when using iTunes 8 on WinXP), syncing with iTunes is out of the question. iTunes has never worked properly for me actually, but v8 is flatly horrific.
