I can't seem to unlock my original sprint iphone 4s to work with MetroPCS. My iphone is running IOS 7.0.4....I have a GPP Turbo Sim For 'ios' and it should work for IOS7 -I've been told. Inisde I have my blank programable sim card, sim eject tool, GPP and GPP tray. I go through all the steps on neterteam and patch my phone successfully, then I program the blank SIM to my original 'US Sprint', then I reboot and put the metroPCS sim and GPP in...but whenever I insert my metroPCS sim w/ the gpp in it, I always get 'No Service." MetroPCS is now using Tmobiles network so when I choose a profile, I always pick Tmobile's profile when using the NETERTEAM program. It should still work right? I tried to force '2G' using the neter 3to2 program on the springboard, but it doesn't really do anything. I can't seem to get a signal at all....just searching to No Service. I restart many times, toggle airplane mode...and always get "No Service" The only time that changes is when I'm searching or right after I program the unblan sim to Sprint...then it occasionally shows Sprint. Furthermore, I tried 'CHINA3GPP' tool the GPP v4.0.exe but am always getting an error when I enter my activation code provided it says registration failed. I don't know if I explained this correctly, I am just as confused on what to do. I know it's possible because many people on youtube comments say their GPP turbo works with IOS7. My iphones also jailbroken and I have installed the cydia.china3gpp.com source. Can anyone provide some input please?
