My son upgraded his IPOD touch to the IOS.
After doing so, there is no music on his IPOD.
If I recall looking into this a while back there was a warning before applying the upgrade, but I do not recall what that message stated to do after the upgrade.
ITUNES looks fine in terms content.
I am assuming that there is a process to get the music sync'd back to the IPOD but I do not seem to be able to locate that process.
