Maybe I am missing something here... but I can tether my phone perfectly fine with my macbook pro without any special apps or hacks.
I pair the phone with the laptop and in the settings i set it up with a default Bluetooth DUN configuration with a blank telephone number. Account name of (phone number)@vzw3g.com and then set the password to "verizon". Connect and it works fine. Why is everyone using all these apps and hacks to do this when its not needed?
