I'm interested specifically about the Incredible because of the Froyo news the last couple of days but in general after the Froyo update should the versions of Swype that were made available still work?
I've been using Swype on FroYo on my Evo for a few days now, no problem.
As long as you are in the beta officially I believe the Swype installer app downloads the correct version depending on your platform (2.1 or 2.2).
