A few tethering applications have appeared in the App Store only to be pulled very soon after. One such application was iTether, it appeared back in November 2011 and was pulled on the same day it launched. The app cost $14.99 and used USB to connect your Mac to your iPhone to use its data connection. The app bypassed the usual carrier tethering charges which probably explains why it was pulled.
Now the developer behind iTether has returned with a new service which is simply called Tether. The new service is based on HTML 5 so there is no need to source the app through the App Store.
"It was clear from our initial application iTether, there was enormous demand within the iPhone ecosystem," says Tim Burke, CEO of Tether. "It was unfortunate that Apple decided to remove our application, only 20 hours after we launched. However, this caused us to innovate. Our underlying patent-pending technology behind Tether for iPhone is unlike anything on the market." Tether's new version for the iPhone is purely based on HTML5 and creates a completely wireless connection over AdHoc. This circumvents the need of buying the application directly from Apple's App Store and allows any iPhone or iPad with a data connection to allow tethering.
Tether is available as a once a year purchase of $30 and is compatible with Windows as well as Mac. There is currently no trial version so you can’t test it before you part with your money. You can see exactly how it works in the video below!
