Yesterday Apple released iOS 4.21 for the iPhone 3G, iPhone 3GS, iPhone 4, the iPod Touch 2nd, 3rd and 4th Generations and the iPad. Get the update now though iTunes.

The battery life once again seems to be better on my iPhone 4 but will see if the improvements stay.

In other Apple News, the “Find My iPhone” feature of MobileMe is now a free service, just add a MobileMe account using your existing Apple ID from your iPhone to activate the service.
