This also works for R-SIM-7 the difference is that the R-SIM-8 and brings the patch (serial) and the R built-SIM-7 patch you have to buy separately. Test for me with version 6.1.4 sprint iphone5
1. We insert the sim with the gevey and we appear a sprint and then choose options iphone5
2. Reboot the phone and wait for the signal from the company you want after that you will be able to tell that the phone does not raise 3g and for that very reason not send messages or data servicion Work (internet)
3. Connect the phone and open on select R_SIM5E_patch unicom.
4. We will ask that we enter the patch which you will be able to see on your gevey
5. After that we give ok and hope to finish the procedure.
6. Finally reboot the phone and set your phone with full 3G signal and data network in version 6.1.4
