how can i disable all internet/data on phone? [Sprint]

[kb2587]

hey all, i have a HTC Touch Pro through Sprint, wanted windows based phone for proggies for hospital use, but don't need/want internet data plan and didn't sign up for data plan when i got phone but now they're charging for individual kilobytes used & running up bill when i havent been online at all.

From under the settings tab, and then under communications i turned wi-fi and dta connection off... however still seem to be getting online somehow... is there some way to turn it off completely going through windows or some other way?

i know there is one program that autoupdates randomly (epocrates) for some reason too... cant figure out how to turn that off (& it's one program i need on phone or id uninstall it)

thanks for any help!
