Questions About Australian Mobile Phone Company

To 3 or not to 3

Australian Mobile Phone Company Filter: Anyone got share-worthy experiences with "3"? I'm considering moving from Optus to 3 because mobile data appears to be much cheaper. I'm probably going to upgrade from my N-Gage to a Nokia 6680 at the same time for the new version of the Series 60 OS and the camera. I'll be wanting to keep my old phone number. Horror stories and/or effusive praise welcome.
