quick question. i know it's a noob question, i'm sorry, but.... if i'm visiting the genius bar to get my ipad looked at do i need to bring the original packaging? i was planning on going in the morning for them to take a look at the yellow spots around the edge to see if i could get a replacement but i don't have the charger it came with at the moment. just wanted to be sure so i don't waste time. thanks guys.
