iPhone Cellular Data: Just Say No

So I got a 3G iPhone for Christmas, a closed proprietary platform, but a fun one :-) We just need to get a python runtime on there :-)

A frustrating thing with this device is the lack of control over its network interfaces. You can explicitly control 3G data and wireless, but not 2G data - this was a retrograde step moving up to the 2.0 firmware. What this means is that if your wireless connections drops, you skip back to cellular data - and even if you have 3G off, you're still unexpectingly racking up 2G data bills. Urrghh.

There is a very easy solution though - which strangely doesn't seem to get mentioned out there on the web that I've discoverd in my brief searches so far. To turn all cellular data connections off, but leave wifi on, just turn on "Airplane Mode", then after that turn "Wi-Fi" on. That gives the desired result.
