I reset my phone and it played alright for a couple weeks, then it slowly quit playing music again, it was almost like a plague because slowly more an more of my music quit playing, from online downloads, bought off iTunes, and downloaded off CDs, they all quit. I took my phone to the local apple outlet and since it was so new they gave me a whole new phone because they couldn't find any faults with the scan they do in the store. The new phone worked flawlessly for about 3 or 4 weeks and just now it's started to quit playing music again. It almost seems like the 4s is disposable as an mp3 player and I'll need a new one every month?
