While it seems reports that Best Buy was holding iPad 2 stock were true, it was apparently not due to a contract dispute with Apple. Best Buy released this statement to BGR

"Best Buy continues to receive iPad 2 inventory from Apple on a regular basis. As we've said previously, we are fulfilling customer reservations first. Our stores have been asked to temporarily hold non-reserved iPad 2 inventory for an upcoming promotion. This is a customary practice for us when there are supply constraints. Best Buy enjoys a great partnership with Apple, and we're delighted by customer response to iPad 2."

The above screenshot does show that Best Buy asked employees to hold sales of the iPad 2 at this time, but no other details are provided. A CrunchGear reader even received an email reply from Apple acting-CEO Tim Cook who denied any knowledge of any issue.
