updating to 4.3
I have a 3rd generation iPod Touch. From my elderly Powerbook G4 (running Tiger) and iTunes I can only update it to 4.1. I found instructions on how to manually update it to 4.3 or I can go as high as 5 if I use a friends iMac. But if I do update my ipod will that prevent me from syncing with my old iTunes ever again?
Powerbook G4, Mac OS X (10.4.11), iMac G3 (10.4.11), iPod Touch 3rd Gen
