They need to do an update...but after reading about a new PDA, we may never see a task list, etc.
There has been an Apple PDA rumor for longer than there was an Apple phone rumor, with much less evidence to support Apple was actively seeking to make a going concern. Just look how well TabletPC has done. My vote is: Apple considers iPhone to be the Apple PDA.
And now I don't give a flip about the iPhone update for today. I just read the Sony's PSN Network for PS3 is confirmed by the developer for getting the Jericho demo today, just like everyone else's system. I can just wait on that, and on that I've got a promise *and* a date.
p.s. Hope it isn't awful. That would be a letdown.
