Been following this thread for a week or so and I'm with several others ... don't really care if it works with Windows and don't really want to buy a new MacBook to have this functionality. Meanwhile, seems as though the first step is to have a Mac-compatible of the Blackberry Desktop software. My understanding is that loading the software is essential to make tethering work on a pc, so it seems logical to start there. Has anyone considered a email campaign to Blackberry/Apple and the various cell carriers to ask for a this? Seems there are a lot of people wanting it. What do y'all think?
