I was wondering if there was anyway to get an iPhone 4, 3GS , or 3G from AT&T or an iPhone 4 from verizon on the straight talk plan from walmart?
True - which is why you would buy the specified phone for that network. Once you receive the phone (i'm referring to the gsm models with a sim) you activate it on straight talk, then you can put that sim in your phone. ie; activate an E71 on straight talk, take the sim out, put it in an iphone 3g or 3gs and your carrier will show at&t under settings/about. Iphone 4/4s will require you to cut the sim first but they will also work out of the box. MMS needs a APN mod to work. Straight talk is a reseller - they resell for att, Verizon, sprint. Depending on the model phone you purchase determines which network you will be using.iPhone4S is the only iPhone that supports both GSM and CDMA networks. There is absolutely no way to use a CDMA iPhone4 on a GSM network.
