Palm has just released webOS 1.1.0, and the changelog is extensive. In addition to " Resolves an issue preventing media sync from working with latest version of iTunes (8.2.1)" you'll find other gems like:
A new NFL Mobile Live application.
Tweaks to the Calendar, Contacts, and Camera apps.
Support for new Exchange ActiveSync Policies (including Remote Wipe).
Emoticon support in text, multimedia, and IMs.
A new forward-swipe gesture.
...and quite a few other refinements. Will Apple and Palm enter into the same vicious cycle of break-it / fix-it that instant messaging applications and protocols did for years, or can we all just learn to get along? Apple, the ball's in your court.
