I ask because last time I went to the Genius Bar the Genius gave me a look when I needed to have it fixed. Instead of replacing it they actually took it in the back and worked on it for about half an hour which somewhat fueled my speculation that they knew it was jailbroken. Sorry for being somewhat paranoid but since I have to go to the store tomorrow for another issue I don't want to be denied. My iPhone is currently jailbroken but I'm planning on upgrading and setting it up as new and restoring it once more to be safe. I'll also install all of my music and apps to try to avoid suspicion.
