Slow
Everything I've seen so far about 3.0 is slow. SMS takes longer to load, Sync takes longer, app store loads slower, apps in general take longer to load. I like the idea behind the update but honestly 3.0 was built for a phone with a better processor. I'm wondering if maybe that was an oversight by the developers. Iphone 3G doesn't seem to have the hardware to handle 3.0 like I thought.
