iTunes 8.0.1 has been released today. It seems a minor update. However, at TUAW people are reporting problems with syncing iPhones. None of these people said whether their iPhones were pwned or not. Anybody with pwned iPhones having problems syncing with the new iTunes?
EDIT: I just synced my pwned iPhone running FW 2.1 with iTunes 8.0.1 and everything went fine, no need to reboot in my case
