I have the phone (4s) jailbroken. When I put in the gevey ultra sim with my activated TM micro sim, it wants to activate and goes to "sim not valid". Is this a fake gevey or am I missing a step. I did this with my daughters phone and got hers unlocked ok using a gevey. If I use her gevey with my sim, will her gevey need to be reset? Or can I swap the geveys with no worry? Don't want to run the risk of messing up the gevey in her phone. Thanks.
