Looking for help on setting my T-mobile 8700 as a data conneciton via a usb cable.

I've seen folks do this at airports and will like a clean way to do same. Thx a million!

Do you mean tether as in use it as a modem? Search on Tethering and you should find a ton of info as it has been discussed several time. Also make sure you have a tethering plan added to your account or you could be hit with a hefty bill. I think T-Mo is the cheapest in that regard.
