Apple on Thursday released an update for the iPhone operating system, bringing the current version of the OS to 3.1.2.

According to notes accompanying the update, Apple fixed three bugs, which may not seem like a lot, but they are important. Among the changes is a fix for what Apple says is a "sporadic issue," where the iPhone would not wake up from sleep mode.

The update also resolves an issue that could interrupt the cell network until the phone is restarted. A bug that caused a crash during video streaming has been addressed in iPhone OS 3.1.2.

Apple said iPhone OS 3.1.2 is compatible with the iPhone, iPhone 3G, and iPhone 3GS. The update is available by plugging your iPhone into your computer and clicking on the update button in iTunes.

Once finished, your iPhone will restart and immediately alert you to a Carrier Settings update. This is a very small update that will be completed without needing to restart again.
