After the iPhone 4 launched I'll admit that the hype got to me, so I decided to reserve one at my local Apple store for launch day. But now that the iOS4 update is out and running great on my 3Gs I'm starting to doubt my decision to reserve an iPhone 4. Do any of you 3Gs users feel the same way? If you don't, then what feature of the iPhone 4 is pushing you to upgrade? Maybe after I see it in the store my thoughts will change.
