Which companies? Hopefully someone like AOL got a copy so we can finally get a damn chat program... Ideally adium!!
The first official chat program will be iChat, which is going to suck until we get Adium or another that supports multiple protocols like MSN and Yahoo.
It's been said a million times...iChat would eat into SMS profits for AT&T, which in turn would eat away at Apple's share of said profits. Don't hold your breath for iChat.
First of all, it hasn't been launched yet, so I doubt companies have it already.
Second...do you really want a company like AOL, with it's festering turd of a desktop chat client, creating software for your iPhone? I certainly don't...but I do hope the Adium developers create a version, that would indeed be great.
Ha ha, 'festering turd', that's funny. It's true too... Does anyone even use AOL anymore? (I'm not talking about AIM, but their software for getting onto the internet)
