Data Connection Disable

[m0nti13]

I've been looking around a bit but couldn't find anything specific.

How do you all disable the data conection after your done with it. I have the touch pro and I can just hold down the end call button, but on my wife's Omnia this doesn't work and I have to go through a few menu screens. I looked through the Settings->Buttons->end key tab, but the only option on that tab is "lock device" radio button and I can't uncheck it.

Any one know of a way to turn on the end call button long press for disabling data connection?
