I've noticed in settings>General>location services that "AdSheet" has appeared. I've searched for AdSheet and only come across problems with those who jailbreak. I have never used jailbreak. I do not have any white icons as those who have jailbroken do. iPhone 4 iOS 4.2.1 I didn't start from fresh, I restored using my 3G backup. I've had my iPhone 4 since release date and this has only occurred since today! Any suggestions as to what it could be or how to remove it?
