I'm probably about to be getting an unlocked iPhone 3G, and I've already got a TracFone. I know that TracFone uses proprietary firmware on their phones along with their SIM cards, which is why EVERY f***ING RESULT on Google is telling me that, but I really don't see how that gets in the way of using the SIM card. Why couldn't that proprietary firmware just be mocked on a jailbroken iPhone to make the SIM / network think that it's a TracFone? Basically, my question is if anyone knows of anything I could put on the iPhone to make it act as a TracFone and work with a TracFone SIM, and if you just tell me that you can't because of proprietary software or the (nonexistent) lack of GSM, I will punch you in the face. Sorry for coming off as rude, but a bunch of idiots arguing is all I've been finding for the bast two hours on Google, and I'm getting really frustrated with it.
