What time should I arrive at Walmart, Thursday morning? I know Higgs1 said they will begin selling iPhone 4 at 8AM, but my local Walmart(s) aren't sure if its 8AM or 9AM. I was thinking about getting there two hours before they sell. I doubt anyone else besides MR members and guests will see the spreadsheet of iPhones available at Walmart at launch. So, is it good timing at Walmart, or should I get there earlier?
