yeah take it in and get it assessed
unless you have been throwing it around and not considered neglect applecare will repair it under warranty
mine is starting to do that also.. its only 2 weeks old. will they give me a brand new one or just fix mine. I would rather a brand new cuz then I will get a 2.4!!
no you're being greedy.
