Bought my 2 a little under a year ago. Mic doesn't work and it's having kernel panics. I'm going to take it into my Apple store a couple of hours away, but has anyone had experience getting a replacement 2? Mine is the 32GB / 3G version, which technically has been discontinued. Inventory in general is in short supply in my area and the 4G iPad hasn't yet been released, so I don't know what they'd swap mine out with.
