At a Web 2.0 Summit in San Francisco on Wednesday, it was announced that an official tethering option for the iPhone is coming soon, according to AT&T Mobility CEO Ralph De La Vega. However, a specific timescale or any idea of pricing were not disclosed.

Tethering is the process of connecting, wirelessly or via a cable, your cell phone to a laptop or other mobile devices in order to use their mobile internet connection. A similar software, an app called NetShare, which allowed users to turn their iPhone into a WiFi-connected modem, was pulled from the AppStore because it contravened the terms and conditions of service.

Apple seems to be in talks with AT&T regarding an official tethering option. Unfortunately for the iPhone users, the unlimited data access that the cell phone users currently enjoy will not be carried over to tethered use. In other words, a strict cap will be implemented to prevent the AT&T network getting awfully busy. TechCrunch’s representative Michael Arrington and Ralph De La Vega described the audience at the summit how the world of an iPhone user will probably look like after a list of applications will be released, besides the tethering option.

The iPhone will act like your wife or best friend: it will make you the morning coffee, bring your newspaper, lock the door on the way out, start your car or help you with your business. Of course, these apps sound a little futuristic, but anything’s possible.

At the summit, AT&t also announced that it will begin using a new swath of 850 MHz spectrum to deliver a clearer, stronger signal in densely populated areas. Furthermore, the company will be market testing femtocell technology in 2009 (femtocell devices connect to wireless broadband networks indoors, boosting the connections of wireless devices like the iPhone).
