As many Q users know, Verizon Wireless does not allow you to use the Motorla Q as a dial up modem for your computer to access the high speed EVDO network.
Thankfully the folks over at Howard's Forums have come up with a tweak that will enable this functionality, allowing Q users to get near broadband speeds with their computers anywhere they get EVDO service.

As always exercise caution when editing your registry. The tweak is available over at Howard Forums.
