Anyone else had a problem with the latest firmware? I installed 2.2.1 today and iTunes crashed when trying to sync. So I rebooted my Mac and unplugged the iPod, thinking it may be to do with another update I had today. However, I have just tried to sync my Touch again, and it crashes iTunes everytime!!! This is the first time I have seen this. I have tried a restore from backup, but the firmware stays the same so it still crashes. Does anyone know how I restore the firmware to the previous version (on a Mac)?
