I got a new blackberry that is registered (when I open Tether on my BB it says that it is registered) and now when I try and connect the two via bluetooth, I get an error on my computer (OS 10.6.4) says that tether is not found on the device.
I'm running an older version of Tether, not sure which version because when I updated to the latest version a few months ago, I could not gain any functionality with Tether since I have a Blackberry Storm 2.
Anyway, Tether aint working and it's driving me crazy!
Could you email help@tether.com with a screen shot of your network connections?
