Best Buy has issued a corporate memo to mobile sales employees, warning them that inventory of the iPhone 3G will be constrained over the coming weeks, and that some locations may run out of stock completely. AppleInsider notes that the internal advisory is similar to one recently sent out by Australian iPhone distributor Brightpoint; the memo also follows a report from last week stating that AT&T is running short on new iPhone 3G units, and has begun to offer refurbished units instead. Supplies of iPhone units have traditionally dwindled during the time leading up to the introduction of a new iPhone model.
