Travel Technology - Help!! Any where to buy a cell phone at MSP?

I'm ready to board a plane to MSP and I just realized I forgot my phone.

There has to be plenty of places at the Mall of America right by the airport.

7-11 stores sell prepaid phones.

Target is a pretty good place to buy cheap prepaid tmobile phones, and since they have their HQ there I'd imagine you can find one or two Targets around.
