The main feature list is really all about the enterprise: IT-initiated remote wipe, required PIN with complexity, device wipe after a certain number of failed PIN attempts, auto-lock, and improved digital certificates. While fun for boring people in suits, there's a whole lot more in this webOS update that's a lot more interesting.
First of all, the iTunes media sync feature has been re-enabled. Apple specifically blocked the Palm Pre from syncing with iTunes a little over a week ago, but Palm is not impressed. "Oh, and one more thing: Palm webOS 1.1 re-enables Palm media sync," the Palm blog reads, "That's right -- you once again can have seamless access to your music, photos and videos from the current version of iTunes (8.2.1)." Oh, it's on. It's on!
As always, the webOS' over-the-air update feature will update your Pre.
