For anyone thinking about camping out at your local Walmart or trying to get it on launch day, DON'T!
Just from my previous camping experiences (launch of PS3, Wii, Black Friday, etc), all of the Walmarts I went to did a stupid raffle for everyone that showed up (even ppl that came when the item was being released, making it not fair for ppl that camped out all night..). I would never tell anyone to go to a Walmart for a launch on ANY items...unless you are on the bad side of me 🙂
You guys should take the chance to go to a local AT&T store (they will have more in-stock compared to Walmart or Radio Shack) or drive to an Apple Store.
