FlashArmyKnife is a multipurpose app in the App Store that is advertised as "7 apps in 1." There's a hidden app/feature that could benefit you until Apple catches on.

FlashArmyKnife contains 7 apps/features into one app. There’s a flashlight, a Web browser, trigonometry calculator, satellite view map, currency converter, compass, and a battery indicator. There’s also an 8th hidden app/feature that will almost certainly get it pulled out from the App Store - a hidden tethering feature that can be accessed inside the calculator app function.

This will allow you to tether your iPhone with another device and use your iPhone’s Internet connection to get online. iDownloadblog has posted instructions and linked to the video below showing you how to use this app for its hidden tethering function.

FlashArmyKnife costs $1.99 but don't expect this app to last long on the App Store!
