It is called tethering, so do a search on that. If you do it, make sure you have the proper data plan which allows for tethering. Otherwise, you could have one really high data bill.
It will be waaaayyyy slow however, only slightly faster than dial-up. EDGE on both T-Mo and ATT average about 50-125 kbps depending on the connection. Max speed is around 300 kbps but it is rare to get that high.
CDMA (Verizon and Sprint) is much faster, 400-800 kbps and max at about 2.4 mbps. ATT's 3G has similar speeds.
