R-sim7 for iphone 4s
I really want to get out from under Verzion's thumb and go to Straight Talk for my service. I kept seeing on youtube and reading about the R-sim7 sim card adapter that will supposedly let you use a straight talk or other carrier's sim in a cdma iphone 4s. I have been getting mixed information on it working for some and not working from others. Does anybody have a definite answer on this?
And yes, I know Verizon is CDMA and Straight Talk is GSM. The iphone 4s has both radios built in so the hardware should support it. Thanks for any help!!
