I keep checking Apple's website daily as well as iLounge (i am sure they will report on it), but Apple only still has the "Open Letter" and no real explanation yet as to how they will issue the store credit. I also have not received any emails from them regarding this matter. Jobs said this week, so there should be an announcement soon. I would like them to hurry up as I should get $200 for two iPhones I bought (and later sold, but still have the receipts). This would come in handy to by myself an iPhone.
If anyone else out there has heard anything, please post here. thanks!
