The new iPod did not come with a charger that I can plug into a wall outlet to charge. Can I use the wall charger to my husband's 4th Gen? Also, wondering if/how to play the iPod contents through my PC at work. Can't download iTunes (not allowed any downloads) and don't know what would happen if I took the USB connecter and plugged it in to the PC. Anybody know? Also wondering how to tell what generation this iPod is. I assumed 5th Gen, but somebody has posted something about a 5.5 gen. What is that? Thanks in advance!
