Anyone know the different between soft-updated 1.1.3 and official 1.1.3?

i know soft-upgrade doesn't update the baseband, but what else?

A soft-upgrade. This updates the iPhone to firmware version 1.1.3, though it doesn't update your baseband, which means that the unlock will remain intact, though also means that you need to install a a few of fixes to get some 1.1.3 features working and some bugs fixed.
