Hey Folks, New to the forum and of course i have a desperate situation: I have a iphone 4 jailbroken running iOS5 on BB 3.10.01. I have a gevey ultra sim and my service is t-mobile prepaid. I put the sim in while powered off. Turn it on and out of the gate, the problem is there's no gevey welcome screen message & it says there's NO SIM INSTALLED. So i decide to go to setting>phone>sim options?>and select the language to prompt the welcome so i can accept but i can't do that because "phone" option is grayed out and its saying NO SIM. What can i do? Does tmobile prepaid not work with Gevey Sims? Is there something I'm missing?
