Apple today rolled out the latest software update for the iPhone, OS 3.1.3. The firmware ugrade fixes a number of bugs (see image below) and, according to reports, wreaks havoc on jailbroken iPhones. The former is entirely welcome. And, while the later isn't welcome, no one should be surprised that Apple's once again reasserted control over the iPhone. Now it's up to hackers to reassert themselves and enable iPhoners to run their unofficial apps again. No doubt they've already gotten to it.

Today's update follows one released by Apple for iTunes earlier in the week. iTunes 9.0.3 provides a number of important bug fixes, including:

--iTunes no longer ignores your "Remember password for purchases" setting.

--Addresses problems with syncing some Smart Playlists and Podcasts with iPod.

--Resolves a problem recognizing when iPod is connected.

--Addresses issues that affect stability and performance.
