Is there, or do you think there will eventually be support for iChat/AIM on the iPhone? Personally, a do-everything kind of phone isn't "do-everything" unless it has instant messaging. If not, I'm getting the newest Sidekick on the 24th...
I think it will. Apple made no comment on the phone's software upgradeability. In the past when they've announced products this far in advanced they've bumped up the specs (first batch of macbook pros?), so I'm sure adding ichat functionality shouldn't be too hard.
