This new ROM update for the Samsung i780 will upgrade the software version from Windows Mobile 6.0 to Windows Mobile 6.1. It seems like folks at Samsung took a really long time to come up with this update especially when the Windows Mobile 6.5 is around the corner.
Note that since this will a ROM update, it will erase all the contents of your device. So, you should do a backup of all of your data before performing the update.
