Upon my research of trying to make a jump to prepaid on my iPhone, I was really left between a rock and a hard place. I had a Verizon CDMA iPhone 4 32GB. Now as many of you know, the CDMA iPhone 4 does not have a SIM card slot. So all GSM carriers were out of the question. The phone was given to me by a friend who had upgraded to the iPhone 4S and then the 5. It really was something I was thankful to have and now I needed to find a use for it.
