An iPhone tethering app, iTether, appeared on the iTunes App Store. It was a direct violation of Apple's anti-tethering policy, but it somehow got approved and was available for download at a price of $14.99.
Basically, iTether would allow users to pay $14.99 once (for the app) and stop having to pay their data tethering fees. The app became one of the top paid apps for iPhone on the US store before it was yanked off.
Withing hours of release, it was pulled down by Apple. We are left wondering who let it go through. Maybe someone is getting fired...
The users who already purchased and downloaded the app should be able to use it normally. And since it reached the top spot on the US iTunes store for paid apps, many people have surely already downloaded it.
