I've noticed quite a lot of talk about the potential release date of the 3G iphone in June. Everybody is concerned about the possibility of a camera, GPS, HD size. These are all great concerns but I was also wondering about the possibility of Iphone tethering an internet connection for a computer or laptop (in my case Macbook Pro). I've been told that many smart phones offer this ability but that iphones currently do not. Is this something that may be improved upon for the next gen iphone?
