TweakTown posted a guide about sharing a HSDPA connection from WM6 phones

In an ever connected digital world, users are doing all they can to stay connected to the Internet. Manufacturers realize this and that is why you are seeing many new types of portable devices hit the stores such as smaller notebook computers, Ultra Mobile computers (UMPC), internet tablets and a multitude of Pocket PC style smartphones.

All of these devices include many data connection options such as regular gigabit or 10/100 local area networking, 802.11b/g Wi-Fi as well as many different mobile phone network connectivity types such as GPRS, EDGE (EGPRS), 3G (W-CDMA) and the newest kid on the block, 3.5G or HSDPA which is short for High-Speed Downlink Packet Access.
