I am currently a Straight Talk user with an unlocked iPhone 3GS and the phone and plan works great. I am, however, definitely planning to jump on buying the iPhone 5 when the time is right. My question though is whether or not to buy a GSM or CDMA based phone. To the best of my knowledge based on my research, I have found that Straight Talk is the best plan if you have a GSM phone with regards to value for the performance you are getting; i.e. $45 a month for everything unlimited. I would even be willing to pay lower for prepaid restricted performance if there is such a thing. As an imaginary example, pay like $30 a month prepaid for a fixed amount of voice, text, and data usage. If there is such a cheap fixed plan, either GSM or CDMA, please let me know. But in general, I want to know if there is a comparable no contract service to Straight Talk, but on the CDMA network for an unlocked CDMA iPhone. From what I see from S.T., they do not support CDMA.
