A minor-update to Apple iPhone Software 3.1 is now available for download, the new iPhone OS 3.1.2 is a bug-fix release addressing flaws from previous version - the new OS update fixes Wake-Up from Sleep, Streaming Video Crash, Lost Network Acces and other annoyances from 3.1 release.

If you have a jailbroken device the iPhone Dev Team has advised not to upgrade as PwnageTool and redsn0w are not yet compatible with 3.1.2 and there is no estimated release time for compatible tools, however, Chronic Dev advised its safe to upgrade as 3.1.2 is just an RR update fixing some bugs and nothing is different at all in iBoot or any other firmware files, adding greenpois0n exploit works just fine with the latest update.
