How big of a deal would it be to repurpose one of those super cheap pay as you go cellphones from Wal-Mart? It seems like if you could strip it down to zero you would have a powerful, cheap, feature rich development platform. Maybe a Windows or Android phone would be a better candidate. I guess it would be necessary to know what kind of processor it has, what kind of firmware it uses, etc. Any ideas/comments??
Maybe I need to buy one to tear apart.
