Apple Updates iPhone Software to 3.1.2

This new release seems to be pretty benign, as it appears to fix a few minor issues.

Resolves sporadic issue that may cause iPhone not to wake from sleep
Resolves intermittent issue that may interrupt cellular services until restart
Fixes bug that could cause occasional crash during video stream

The update is available through iTunes now. On a side note Apple also updated it's SDK yesterday to match the 3.1.2 update.
