Apple, who currently have an Apple iphone Developer Program account, has recently launched a new beta version of iphone OS. On AT&T ' s network, Internet tethering can be setup. Though AT&T doesn't necessarily want or allow any tethering, Internet tethering was discovered by someone over at MacRumors forum.
Though AT&T doesn't allow any tethering, we hope that when Apple decides to launch the new iPhone 4G/HD, this feature will come. The new iphone OS beta can be downloaded at Apple's website but only if you have an Apple iphone Developer program Account
