Well, my original iPod touch was faulty, so I took it to the store and got it replaced a month ago. Now my replacement ipod has some bugs that I want to know are normal or not. -Randomly doesn't switch to coverflow mode, sometimes instant other times, other times never at all. -Battery life at 3.5 hours video with default setting but wifi off. Promised 5 on website. Should I go back to the Genius bar and get it fixed? or it is normal?
