Nokia :: 5230 - How To Display Letters On Dial Pad?

Just about every one of the 6+ Billion telephones on the planet displays letters on the number keys, ie. ABC on #2, DEF on #3, and so on.Why is it that Nokia cannot see fit do do the same on the 5230 dial pad?
It can't be that the 'real estate is too small - LG manages to do it just fine on the Xenon GR500FD phone with smaller on-screen buttons.The lack of letters on the dialpad makes it extremely difficult to interact with IVR systems where you need to be able to dial by 'last name'think calling a large company or hospital when you don't know the person's extension.Has anyone found a way to mod the 5230 dialpad to display letters & numbers on it?
