Apple released an update for the iPhone today that’ll take you from 1.1.3 to 1.1.4. It’s 162 MB and doesn’t seem to do much for the iPhone’s feature set. With that said, it’s probably safe to assume that a small percent of the MBs are dedicated to fixing bugs while the remainder is in anticipation of the SDK.
To nab the update just hit the Update in iTunes to 7.6.1
