Guess what’s just been seeded to developers? The Gold Master of OS X 10.7 Lion… the last developer seed before Lion becomes available for download to all Mac users through the Mac App Store. What a way to start off the holiday weekend!

We’ve seen and loved Jan-Michael Cart’s incredible iOS 5 concept videos before, but his latest might be our favorite yet: it shows how Apple could bring OS X’s Dashboard feature to iOS 5.

Apple has released an update to its Mac OS X 10.7 Lion beta. The 1.24 GB update is third build of the new operating system, which is expected to be shown off at WWDC in June and released to the public in the summer or fall.

The update is available to registered Mac developers running Lion Developer Preview 2. It can be downloaded through Software Update. The release contains no release notes and appears to contain only minor UI tweaks, according to tweets crossing the wire. It’s unlikely to be a big update. That will come with Developer Preview 3.
