Once upon a time, you could purchase a tethering app from Apple’s App Store. Netshare allowed iPhone 3G owners to tether their iPhones with their laptops, through a WiFi connection. Tethering allows you to use your iPhone as a mobile broadband connection for your laptop. AT&T did not want this to happen, since you would normally pay extra every month to tether other phones. The reason for the extra charge – you could use up a lot more bandwidth in a shorter amount of time than what you could do with your iPhone by itself. People even wrote Steve Jobs about it, and he agreed and said it was being discussed with AT&T.
Now those talks are coming to fruition – MobileCrunch mentions that an interview with AT&T Mobility CEO Ralph De La Vega during this week’s Web 2.0 Summit revealed that AT&T has plans for an official plan “soon”. No idea on pricing or availability or bandwidth caps. People can use work arounds to unofficially tether their iPhones and notebooks, but an official version would be welcome.
