HTC Dash / S620 / S621 (Excalibur)

I don't have broadband in my area but use my Dash connected to my laptop for a marginally fast Internet connection. My question is, "Is there a way to connect my Dash to a wireless router and then be able to use the connection on other comps(or my PS3) in the house?" What cables should I use and will a router initialize/recognize my T-mob internet connection.

Havn't physically tried this yet and thought that someone else may have and could enlighten me.
Thanks for any input. Michael
