What I'm wondering is if there is a way to delete words from the lexicon of suggested words. The feature can be so glitchy at times that you end up approving words (usually non-words) via the tempermental touchpad that seems to have a mind of its own.
I've seen ways to add a word, but not delete one. On the non-swype keyboard (2.3.4), you can press the little carat chevron to the right of the suggested words, and you will see a flyout menu of more word options, and a button that says "add word"- that's the one you want.
I can't find a way to delete the non-words that randomly get created... just another wonderful android attribute. GB is sure better than Froyo, though.
