Has anyone ever brought a Jailbroken iPhone to the AT&T store?

I'm going today, not to swap it cause it's broken, but to renew my contract and get a new iPhone 4. Don't tell me to RESTORE it because I'm not gonna do that. I just want someone who ACTUALLY did this and tell me what happened when you did. Like the response from the store people and stuff. And whether they gave you a hard time when they saw that the phone has been jailbroken.

You might not want to make demands to the people you're asking to help you.

Yes, they will give you a hard time. They have an emergency panic button, so that whenever someone brings in a jailbroken iPhone, they press it - triggering a lockdown and flashing red lights with buzzers.

Seriously, kid, they don't give a s***.
