Yeah, you're right. I think going forward, unless they actually do add a projector to it, the iPhone 4's design will be the last big change (unless they up the screen size, which I would hate since with so many apps already trailing with the Retina Display upgrades, that would be even worse.) and everything else will be power bumps and battery life bumps. I wonder what iOS 5.0 will be like?
Haha, imagine if we ever get to the point with iPhones that we're at with Macs, where it's like, "I have all these apps, but they only run on iOS Mobile 7.0, and not iOS Mobile X, so I have to run my iPhone in iOS Mobile Classic mode to play them." :lol
