Search and Browse the Web without Leaving a Trail of Crumbs
Personal iPhone/iPhod touch privacy is top of mind for everyone these days, which probably explains the sudden influx of apps — such as PrivateWeb, Privateer and Anonymous Web Browser — into the App Store that promise to wipe the trail of crumbs you leave behind when you're on a surfing safari.
These apps are useful if you share your iPhone/iPod touch with a nosy relative or neighbor. They might also come in handy if you happen to leave your handheld on your desk at the office and the guy in the cube next to you decides to mess with it when you're in your manager's office explaining why you spend all your time surfing instead of working.
