bluedodge,
You are not the only one having this problem. For that reason alone I would wait the 6 days you have left, because a fix may be released in that 6 days, or if not a fix then another solution may be announced.
But if you must return it, I would speak to the manager at Best Buy and tell him what you have tried and ask him to waive the restocking fee. If he doesn't want to waive the fee then swap it for another iPad (if they don't do this they suck and you must burn down the store) and see if you have problems with that one too.
Good luck.
Yeah will probably wait till the last day and do this if I must. I really don't want to return it. I hope I can explain the reasoning to someone at Best Buy and they will understand. I really am trying everything I can.
