Today Palm released a twelve meg update for the Palm Pre – the OS 1.0.4 update - which killed the ability to homebrew apps without "rooting" your Pre. Which, if nothing else, makes the recent SDK leak even more timely.
After updating you may get some errors, but don't fear, for a simple reset will fix the problem.
We updated our Palm Pre to 1.0.4 (by the way, Palm makes you update whether you like it or not…BUT, you can cancel the update.) After updating, we got the error above, and had to reset the phone. After resetting, the phone began to work perfectly normally. As usual, keep in mind that it's always better to wait rather than jump into the update. Let the others (like us, as you can tell by this article) test it for you first.

Also in the Palm Pre universe, much like the "Spy Vs. Spy" dual going on between Apple and the Dev-Team over jailbreaking the iPhone 3GS (see elsewhere in this fine bloggeroo), Palm is crossing swords with homebrew programmers, who are ready to write apps and exploit chinks in the armor of the newly-minted Pre. The 1.0.4 update kills the homebrew hack, so if you don't want to lose it, stay away from the update. However, at some point Palm updates your device without your confirmation.
First up, the leak of the Pre SDK (a/k/a "Mojo"), months ahead of its announced late-summer release. Someone apparently took advantage of Palm's early access program and decided to share the wealth, publishing the entire SDK as it was. PreInsiders has numerous links to the SDK, both web and torrent based, but be aware that (a) this should be treated as a sneak peak/guide to the official SDK release, and (b) they'll dump the links if Palm cries foul. Bear in mind, too, that ANY applications created at this point are not supported by Palm, so do this whole Dexter's Laboratory thing at your own discretion.
