If you look through your modem scripts folder, you might notice a new one if you ran the 10.2.3 update. I might be wrong, but i don’t remember downloading a Sprint PCS Vision script from anywhere, so it looks like it came with 10.2.3. Thanks Apple!

Be sure to turn off TCP header compression, and set the modem script to Sprint PCS Vision. If you don’t have one already, you’ll need a USB cable for your phone. Sprint took them off the market, but Sanyo Wireless is still selling them, and I think there are a couple other places too.
Its painful being away from college where there is 802.11b wireless everywhere on campus, but hooray for unlimited data with my US$45 voice plan!
