Just to be clear. I also use StraightTalk, but here in Colorado, they are an MVNO for Verizon. Carlos Slim's organization has been able to cut MVNO deals with all 3 large US carriers I believe, and it's easy to understand the leverage they have (i.e. want your customers to be able to roam in Mexico?). I've thought about getting a smartphone and fooling the network to believe I have a feature phone, but I have abstained and simply use an iPod Touch (w/ SIP client) + a feature phone. It simply seems like too much effort for me right now.
