Apple Releases iPhone OS 3.1.3.

Apple releases iPhone OS 3.1.3 (7E18) to address a few issues including the accuracy of battery level in iPhone 3GS, third party apps compatibilities and crashes related to Japanese keyboard.

No, this is not the iPhone OS 3.2 as in the iPad, let alone the rumored iPhone OS 4.0 that will be an A+ upgrade just like what Steve Jobs allegedly said.
