I don´t think iPhone 2.0 owners should be thankful that Apple made OS 3.0 available to them too. I really think it´s a given. The only reason why they would not get 3.0 would be if the hardware is not capable of running the software. Any other case would just mean Apple witholding software in order to sell new hardware, which is what they might try to do with the video capability feature. I for one would find that very disturbing. I have not even had my iPhone 3G for 12 months, so I think it would be way too early for a new model to be introduced....
