I also saw something about this recently in regards to Sprint PCS phones and the wireless web option. I beleve that they have released software that allows you to use their internal modem inside their phones with macs. As for hardware compatibility, I think you may have to use a keyspan USB-serial adapter. again, I've never used this, but am about to enter into the same situation you are in. I would like to see more people respond about this topic. I plan on buying a new iBook in the near future and also getting a new digital phone also. I'm also wondering if using the phone this way somehow charges at a different rate, under the "wireless web" pricing scheme. Man, this is sooo complicated....
