iPhone 4 arrives at Walmart (update: and Best Buy!)

Check out that sweet, sweet box. Yes folks, we seem to have received our very first in-the-cardboard picture of the retail iPhone 4 out in the wild. We don't work at Walmart, so we can't verify this one for ourselves, but our tipster says Apple's latest phone has just landed in the big box retailer's storehouses.

P.S. -- Before you start frothing at the mouth, the CDMA coding on the box in the background relates to an LG 290C handset also stocked by Walmart.

Update: A shot of a Best Buy arrival is past the break.
