What do you think would happen?

I really hope that no one would be stupid enough to do this... But what do you think a genius would do if you brought in your jailbroken iPhone? Would they take it away? Go on a rant about all the 'bad things' about jailbreaking?

I think they would respectfully tell you that it is not covered under warranty, hand it back to you, make a note in your account, then follow you out of the store and ask to play with it/ how you did it. :p

All but the last. Most of the Apple Genius' have their phones jailbroken.

The worst that would happen would be that they note on your account that you JBed your phone and thus your warranty is voided. They wouldn't/couldn't take your phone.

Tell you "Sorry you have unauthorized software and therefor we have to decline your warranty claim, if you want a fix for the hardware outside warranty, it's $199." They might tell you restore thru iTunes to get rid of that....
