I have an iPhone 4 and I wanted to update to the iOS5 but I have to update my iTunes to the newest version. Now my iTunes freezes any time my phone is connected. I cannot sync my phone and I decided to just try to do the update but after it was done downloading the update it started to do the phone backup and stayed on the backup progress bar for over 45 mins when I decided to just give up. Before that I had tried syncing my phone over 10 times and each time it froze. I had to use the task manager to close iTunes because it wouldn't close. I have tried to repair iTunes with no luck. I don't have my music backed up anywhere so I don't want to uninstall iTunes, plus I don't want to lose my old phone backups (most recent last week) in case something goes wrong in the update. Has anyone else had this problem? Does anyone know of a fix?
