Can I turn off the touchscreen on my Blackberry Bold 9930

Hi, I have a Blackberry for one primary purpose: To text and email. I also use the calendar and a couple of other simple features. But mainly I need to type and send messages. I have a habit of resting my forefinger towards the top of the phone on the face of the screen which activates the touchscreen and causes the cursor to leap about while I'm typing. I would really like to just turn the touchscreen off. Is this possible? If not, do they make Blackberrys without touchscreens anymore?

Thanks!

no you can't turn off the touch screen. Hold the phone differently. It should stop if you adjust your grip.
