Oh damn, just when we got our Kindle jailbroken running native apps and unlocked for use on T-Mobile, along comes the 28MB v1.0.4 update. We don't know what it fixes or changes specifically other than "overall improvements to performance" and "new screen savers", but it's first Kindle update we've seen since the device's launch, and it's out now. Let us know if you spot anything out of the ordinary, yeah?
Update: Snap, our update failed out. Like four times. It didn't brick the Kindle but it sure as hell killed all our e-books and now the device says it's got no remaining storage. Thanks! More after the break.
