iPhone 4 Spotted At Walmart

As we all know, Walmart will be among the handful of retailers to carry the iPhone 4 on the first day of availability - an unprecedented move in the history of new iPhone releases. Best Buy and Radio Shack will similarly have the device come Thursday. An unknown "tipster" sent Engadget the above photo from one of a stash that's being delivered to Walmart stores in preparation for launch.

Apple has also been contacting those lucky 600,000 souls who managed to place a pre-order for the device to let them know they can expect their new smartphones on June 23 -- one whole day before official launch day.
