I'm so glad that this was announced at tmw... I have been waiting for a way to use my Ericsson t39 with my iBook for wireless internet access. the problem was that before now, i could only use a usb cord which cost $100US+ and was pretty pathetic (unreliable connections, 9.6K only, os 9 only).
Kudos to apple!!! You have answered my prayers!
btw, any news on whether the bluetooth link will work on older machines (powerbook g3, in particular)... if anyone knows, plz post!
