So I have installed a custom iOS 5. And when I try my Gevey sim it works perfect. But when I do the jailbreak I am no longer to do the manual Gevey unlock. I have to initiate the startup from my settings and after I dial 112 and I switch on airplane mode it says invalid sim as expected, but as I wait for it to say "no sim card installed" instead it gives a "no service" and starts to search for network. What do I do ?
