Can I transfer my purchased apps from iPod Touch 2G to the new iPod Touch 4g? I bought the iPod Touch 2g 8GB about 2 years ago and I now want the iPod Touch 4g 32GB. Is there a way that all the apps and music I bought on the iPod Touch 2g can be transferred to the new one I will buy?
Yes - I had to do this for the same devices: 2G to 4G.  I think I just synced the new iPod Touch (there is no such thing as an iTouch) with iTunes, and everything went over, but I might have had to restore a backup from the old to the new.
