Answer to: My ipad fell on the ground and than this.Looks like you have a bad motherboard. It probably was damaged in the drop. Either from the shock of the drop, or maybe a cracked board. Best bet is to have a professional take a look at it for you.
Answer to: Remove the headphones & the iPod touch freezesI would try changing the headphone jack. It is probably shorted out. If you need more help, ask me. Chad
