Palm itself had warned that the Pre's iTunes sync functionality could be broken at a moment's notice (and at Apple's whim), but we're pretty sure no one expected it'd happen this quickly. Version 8.2.1 of the software apparently prevents the sync from working, meaning that you've got to add music the old-fashioned way -- the Pre functions as a USB drive, too -- until Palm gets around to patching the hack (if they decide to patch it, that is). This could end up being a protracted game of cat-and-mouse, which is entertaining to watch but nightmarish for the consumers down in the trenches actually trying to use this stuff. It's unclear whether Apple threw a banana peel under Palm's path on purpose, but it certainly seems that way, doesn't it? We're still confirming whether this is actually broken -- stay tuned.
