After using my 3G iPhone for about a week, I have noticed a couple of oddities/differences from 2G. 1. Missing Artwork. It will appear on the iPhone then disappear on the next sync. Sometimes it will reappear if I fiddle around with the original files on my computer and sync again. Sometimes it won't. 2. Now Playing. The 2G remembered which song I was playing even after I watched a video. The 3G doesn't. Maybe the 2G feature was actually a bug that got fixed?
