PPCGeeks - Touch Screen Not Responding at all, can I access where you switch to GSM mode?

Ok well my LG G2X kept restarting itself over and over when I turn it on so its going to be sent out for repair after 3 weeks of use....damn.

But anyway, since I was using simple mobile, I just need to slap the SIM card back in my old HTC TP2 and switch it to GSM mode and whalla it usually works fine. Unfortunately, all of a sudden the touch screen is not responding to the touch of a finger at all. All I have to do is change it to GSM mode on the phone. I got to the COMM Manager from the keyboard, but the problem is I cant select the "Phone" tab with the "enter" button on the keypad. When I push "enter", all it does is keep turning the phone on and off like airplane mode. This is usually the way I get to the place where I can switch the phone to GSM mode, but I cannot push the tab on the screen.

Is there a way to navigate to where I have to go with the keyboard or does anyone know what is wrong with it all of a sudden?

Please help, I need a phone to use whole the new one is being repaired. Thank you.
