Nextel (I think) New Commercial

[Parpyparpy]

This one has two fat black guys, like overly huge they almost look like m&ms. Anyways one is in some studio or something and one is in a pool. They both ask where the other is and start laughing, because they have the new locator phone or whatever. At the very end it plays the hook of this rap song from several years back. I forgot what it was called and its killing me.

Any help would be greatly appreciated.
