Tried Swype 3.9 on my HD2 and while there are some improvements in terms of layout and key size, it's actually quite unusable for me because the "hold for alternate character/symbol" function doesn't work properly.
I find myself having to aim for the upper right corner of a key (where the alternate character is displayed) just to get it working. This makes writing symbols very inconvenient.
Swype 2.0 doesn't have this problem so back on that one for now until they fix the hold key issue, as well as the problem that typing too fast makes the keyboard think you're swiping (admittedly 2.0 has the same problem)
