In a cat and mouse battle, the style of which Apple is familiar with following similar exploits with the iPhone unlockers, Palm has re-enabled iTunes syncing for the Pre.

After Apple blocked the smartphone several times from syncing with iTunes via iTunes software updates, Palm has used a questionable work-around to make it possible again.

The solution is so questionable in fact, it has drawn the attention of the the USB Implementers Forum (USB-IF), as it fools iTunes into seeing the Pre as an iPod by product numbers reserved for Apple's hardware.

Palm makes no bones about its intentions - the release of webOS 1.2.1, "re-enables the ability of Palm media sync to work with the current version of iTunes", Palm's director of online communications, said in a blog post.

The ball is in Apple's court now, and it will be interesting to see if it responds with another tactical update, or takes things further via the USB-IF.
