You will want to install the VZAccess Manager software, located on a separate disc than the Blackberry User Tools, which is where the Desktop Sync software is located. I sync 3 computers and tether my laptop which is one of the sync'd units. It works well, although it is certainly slower than a data card. Much cheaper though, and works in a pinch.
