I haven't seen anyone mention this in the general forums, but there is a well-hidden ability to edit Swype copy ... slide from the Swype symbol button to the ABC button. Suddenly, you have a keyboard FULL of editing options!!
It appeared accidentally on my screen this morning (I thought at first maybe 2.2 had loaded overnight - no such luck!). It took me a long time to figure out what I did to get it. I pressed and held the Swype button and Lo! instructions for using Swype. There's an index and under "editing," there it was.
Perhaps everyone else knows about this, but it is a super bonus as far as I'm concerned. The DX never ceases to astound!
That is so cool. I really didn't think there was much more. Love that number pad.
One thing I've found useful is the a ability to add custom words that have numbers and symbols, great for logging in using cryptic passwords and such, email addresses too.
