Okay, some of you saw my initial failed attempt at this mod, for removing the 'end call' virtual key / button on the screen, while a call is in progress.
The purpose of this mod is to prevent accidentally hanging up on a caller, by having your face press the 'end call' virtual button. There are even apps in the market to try and address this, so I'm guessing the issue is widespread for people.
On my first attempt, I inadvertently removed the entire bottom row, which was problematic, as it prevented you from being able to enter numbers, etc, during a voice prompt.
I was unable to find a way to remove JUST the 'end call' button, without removing the entire bottom row, so I decided to take a different approach, which is the end product posted here.
This approach seeks to simply disable the key press event on the 'end call' key. This way, we don't have to worry about removing the button, just disabling its function. As a result of disabling, I then went and removed the 'End call' text from the button, and turned it from red to gray, to essentially show it as disabled / non-functional.
To end a call using this mod, simply press the 'red' end call hard key on your phone.

EDIT: After some additional tinkering, I was able to find a way, through a combination with the original mod, to now remove for display the button all together. The original .zip has been updated accordingly.
This mod may not be for you, but if you frequently experience this sort of problem, hopefully this helps.
