iTunes doesn't recognize my iPhone...Please Help!!!

[iBabe]

My iPhone is working great, no problems at all, it is jailbroken and unlocked still on 2.1 but when I try and plug it into my computer and use iTunes it tells me something like "The sim card in this iPhone does not appear to be supported" and it's been doing this for about a month now. Over in the left hand panel area it will say Andi's iPhone and show that it's charging, the first month I had the phone unlocked/jailbroken and all and it worked just fine. Please someone help me I don't know what to do, thanks.

You have rebooted your iphone and your computer im guessing since you have had it happen this long.
Try popping your sim card out in then back in.
Re-Download Itunes maybe that will help, i hope so.
