Users looking to use their iPhone once again as a modem might be in luck, as a recent e-mail, allegedly sent by Apple’s CEO Steve Jobs, explains that the company is discussing with AT&T the possible upcoming release of a tethering plan for the device.

This means that the iPhone could be used by consumers to connect their laptops or computers to the phone’s 3G network and surf the Web. This rumor might just be accurate, as the service is already offered by AT&T for other phones.

The decision to develop such a service was quickly reached as soon as the AppStore started offering an application named NetShare App, which enabled users to connect their PCs to their iPhones and access the Internet. AT&T realized that there was a lot of potential behind such a service and immediately demanded that the app be removed from the AppStore.

At this point, in order to ensure that no other such attempts will be registered, AT&T’s Terms and Conditions column clearly states: “Furthermore, plans (unless specifically designated for tethering usage) cannot be used for any applications that tether the device (through use of, including without limitation, connection kits, other phone/PDA-to-computer accessories, Bluetooth or any other wireless technology) to Personal Computers (including without limitation, laptops), or other equipment for any purpose.”

So far, the legitimacy of the e-mail remains under a question mark and if Apple keeps its current marketing schemes, a confirmation will only be released much later. Of course, AT&T could have a different take on things and decide to offer additional information about their upcoming plans.
