Apple rolled out iPhone OS 3.1.2 Thursday afternoon with a fix for users that have been suffering from an issue that prevented their iPhone from waking from sleep.
The update also addressed an issue that left some iPhone owners without a cell signal until they restarted their handheld, and corrected a problem that could cause crashes when streaming video. Apple isn't elaborating on what else might be included in the update.
iPhone OS 3.1.2 is available as a free update via iTunes. To install the update, do this:
- Launch iTunes.
- Connect your iPhone to your computer.
- Select your iPhone in the iTunes Library list.
- Click the Summary tab.
- Click Check for Update.
- Click Download and Install.
Some iPhone owners have been reporting that after installing the OS update, they are receiving a carrier settings update as well. So far there isn't any information available about what the carrier update includes.
iPhone OS 3.1.2 is available for the original iPhone, iPhone 3G and iPhone 3GS.
