QuasiDisk, a new file manager for the iPhone, has snuck into the App Store with a hidden talent that’s sure to get it pulled pretty swiftly. The $1.99 app doesn’t just provide a quick and simple way to transfer documents between your devices, but also the ability to tether your iPhone’s data connection with other devices via proxy.
That means you can share your 3G connection with other devices, such as your MacBook or iPad, without paying your carrier to use the iPhone’s built-in Personal Hotspot feature. Of course, this is illegal, and it’s one of the reasons why QuasiDisk is unlikely to retain its place in the App Store.
But QuasiDisk isn’t the first — and it probably won’t be the last — app to provide a hidden tethering feature. A number of other releases have attempted to provide iPhone users with a method of avoiding carrier tethering charges, but after just a few days in the App Store they’ve all been pulled. Which is exactly what will happen to QuasiDisk as soon as Apple discovers its dirty little secret.
