Since i have installed and jailbroken 3.0 on my 2G, everything is working fine except when i plug my phone into iTunes, it wont back it up. It shows the message " iTunes could not backup this phone because the phone was disconnected". I never disconnected the phone so does anybody else get this message? And what can i do so when i sync the updated music, contacts, etc will get backed up? Is there a solution to this?
