Downloaded the SIPchange.CAB from here, found it in other posts too, and the latest
PocketCM Keyboard from its site.

Seen the directions, tried them all, that I found.

PCM is under options, but it's for voice recording,
not the keyboard:

Settings > Personal > Input

select Keyboard from dropdown and the only options tab is at the
bottom 'options' tab and thats for voice recordings.

Select PCM, nothing.
Tried combination of installing, reinstalling, soft resetting etc.

Selected form the arrow by the keyboard icon in apps.

Tried holding down right enter button.

So was attempted on a Sprint HTC 6800 Mogul Titan with SPB Mobile Shell 3.

What silliness I'm a doing wrong or what have I missed or flew over?

Thanks for the help.
