Jailbreak and sim card

[geri]

I am having a little troulbe with my Iphone voicemail, so AT&T said I need a new sim card which I have to bring back to AT&T store and they will replace the sim card. My problem is I jailbroke my phone, does that have anything to do with the sim? Will they be able to tell I jailbroke my phone only by replacing the sim card? Should I restore my Iphone before I bring in. Also if I back up my phone then restore, when I restore my backup will it restore the jailbreaking or do I have to do all over again?

You can bring it in to swap the sim card with no issues. If you are really worried about it take the sim card out of the phone yourself when you get to the AT&T store. If you restore you will then have to restore to a new iPhone and jailbreak again.
