Download iPhone OS 3.1.2 IPSW

In what is a rather surprising move, Apple has just released a new update to the iPhone OS, bringing the software version to 3.1.2 in just under a month from the release of OS 3.1, the latest major update for iPhone and iPod touch owners.

According to the release notes issued by Apple today, the iPhone OS 3.1.2 update contains bug fixes and improvements, including fixes for a sporadic issue that may cause the iPhone to not wake from sleep, an issue that may interrupt cellular network services until restart, as well as a bug that could cause occasional crash during video streaming.
