I've got an iPod Touch 1g and a 4g. The 1g still says the "iPod Sync Complete" message that it's safe to disconnect it in iTunes 10.6.1, but my iPod 4G, which I recently upgraded to iOS 5.1 from 4.x, doesn't say any such thing. The sync wheel stops spinning and if it was saying anything about copying photos or whatever; that disappears. But I just find it strange that it would tell me it's safe to disconnect for one but not the other or is the new iOS 5.1 completely OK with you disconnecting in the middle of a sync? I'm using an old PowerMac PPC for my server so it cannot sync via WiFi, so I would have thought disconnecting it in the middle of a sync would be a bad thing. More to the point, I just like the message to know for certain exactly when it's done. Does everyone else's iPod 4G with iOS 5.1 behave that way or is something amiss here?
