I just got an AT&T iPhone customer survey and I notice they ask me to rate my experience using iChat over WiFi. Did they let the cat out of the bag on whats to come or did they intend to say SMS?
Hummmm........
Odd that is does call it "iChat" while the SMS application is called "Chat"
I really hope so - I also noticed that all the plans only allow 200 SMS text messages (unless you pay an additional $10 a month); iChat would be a wonderful way around that
where did this survey come from? Who was it sent to? I didn't get one.
I'd love to have iChat, but hmmmm, just askin'
I did the survey from Apple and it asked me to rate "SMS" and not iChat or Chat. I have a feeling that this was just a typo, but of course I hope it is not.

I would only use iChat on the iPhone while in a WiFi hotspot, since I would not be able to answer calls if I were using iChat on EDGE.
in case no one has encountered this, voice takes precedence over any edge communication. you can do whatever you want over edge, and if a call comes in it cuts off your edge communication and asks you if you want to take the call.
I wonder if IMs will be billed as text messages or data.
According to Engadget's review of the iPhone:
"AT&T's EDGE network can't support simultaneous voice and data. Read: if you're moving data to or from your iPhone, calls will go straight to voicemail."
