i know everyone on here is against going to Walmart, but i camped for 3g and 3gs, and it's a pain especially in the Vegas heat ( it's 80 degrees at night) to wait even for a couple of hours at my AT&T store. Do any Wal-Mart employees know the SKU or UPC for iPhone 4 16gb ? the store closest to me at the electronics department won't give me any info, but I know the UPC/SKU is universal to all Walmarts. I'd have some peace and mind knowing if Walmart is an option if mine gets atleast 5 which i hear is the max as of current even in their busiest stores. any information would be appreciated, please don't bash my question. Thank you !
