A memo is now reaching Wal-Marts from corporate regarding the 5 PM rule. I was calling Wal-Marts and got a department head on the phone. Said he just got a memo from corporate and that they arent to be sold until 5.
Something similar happened to me last year. I managed to get a Wal-Mart to sell me an HTC HD2 phone a few days earlier then release. I posted pics and everything and it made it to many tech sites. The same day Wal-Mart corporate sent out memo's blocking sales until the release date. Reminds me of then, I dont think Wal-Mart wants to piss anyone off.
I think Apple has a BIT more clout than HTC
