If you’re one of the 600,000 people who bought a Samsung Intensity (SCH U-490) or Samsung Trance (SCH U-450): good news! You’ve got an over-the-air update coming your way. One of our sources just came through with the patch notes for both handset’s respective updates, which are scheduled to begin as early as tomorrow.

There’s nothing too major on the update list here, so don’t expect to wake up to find your phone magically jam-packed with new features. With that said, a few of the soon-to-be-fixed bugs sound pretty annoying – so at worst, consider it a bit of polish.
