I have a jailbroken iPhone 4 running 4.3.1 w/ 4.10.01 unlocked with Gevey Sim Pro. I'm on T-Mobile. Regarding Facetime, I do have it turned on, but it just says "waiting for activation"... and I got a message pop up saying something like "your carrier might charge mms fee to activate facetime"... now what? PLEASE HELP!!
