Hey Enyo Folks,
I've been trying 2.6-dev for making HP/Palm webOS ipks and with Jason Robitaille's expert help I've had some success!
I do have an unsolved issue with selection highlights appearing on text and other elements in webOS 2.2.4 (not an issue in 3.0.5), but that is the only nastiness I'm stuck on at this point. I've written a bit about my experience over on webosnation:http://forums.webosnation.com/webos-development/330979-enyo-2-7-aka-2-6-legacy-luneos.html
I generally try to not cross-post, but since there are so few folks left trying to work within webOS 2.x, I figure I can make an exception. I love to hear either here or there if anyone has some ideas about the selection highlights!
