Will it be possible to tether the phone's WiFi connection? This would be very useful in connecting a laptop to AT&T's free WiFi connection for iPhone offered in most Starbucks and other places.
You do know that McDonalds Wifi is free in the UK to everyone, don't you? It's not an iPhone thing. McDonalds subsidise The Cloud. So, you can wifi direct from your laptop.
iPhone does get The Cloud and BTOpenzone everywhere though....
Have you tested this using a bandwidth speed measure website. I tried this and it kept the speed down to 3G speeds, also, the 3G data counter in preferences->usage counted up. That only happens for 3G data usage, not wifi.
I don't think this works. I also tried turning on airplane mode then using wifi on the phone to tether, no dice, wont do anything until i turn airplane mode off.
