I have an iBook G3 700mhz, 384mb RAM. I'm in a bit of a sticky situation and need help. I have a 2nd gen MC model 8gb running 4.2.1 and my brother has a 1st gen 16gb running 3.1.3. On my ibook I have itunes 9.2.1 which is the newest version available. The 1st gen syncs but the 2nd gen doesn't... I like the 2nd gen SOO much more but want to be able to sync it with iTunes. Can I downgrade the version on my 2nd gen so it CAN sync with itunes 9, or am I stuck with the 1st gen? I'm stuck between a rock and a hard place here... PLEASE HELP!!!
