I was looking at AT&T refurbished iPads and thought of picking one up. $429 for 32GB 3G looks awesome but I wanted to know if it has any smudges or any other cosmetic defects. Also it comes with only 90 day warranty, can I purchase Apple Care for it separately? Apple's online store tells that all refurbished iPads come with new battery and new outer shell, does AT&T iPads also come with those? Thanks in advance Oops posted in the wrong section, some mod pls move it to the iPad section.
