can't answer incoming call

I've searched and read the other threads, including the essentials one that tells you to change the GPRSetc back to #777

That works fine, but here's the issue.

I used DiamondTweak to disable my data connection automatically after 15 seconds. When I change that, it puts that registry back to the GPRS thing.

so I change it back to #777 and then I go back to Diamond Tweak, and the disable data connection option is set to disabled.

So I can't have my cake and eat it too??

Running stock rom(just done tweaks with the diamond tweak) Telus HTC Touch Pro.

Thanks for any help that can be provided!
