What can happen next WWDC? I don't know, front facing camera, and a xenon flash? iChat? Who knows?
And seriously, besides the speed bump, I really don't find the other features worth the trouble (and the money). I am really paying the extra god knows how much to load peggle that 5-10s faster. Although I seriously wish that my phone was a little (much) faster, I bet iPhone firmware 4.0 will make the 3GS crawl as well, and by then it will be iPhone 4G or 3GSS or some fuckshit, claiming that everything loads in no time at all, boasting PS3 quality graphics at 60FPS. I wish. LOL.
