iPhone Firmware 2.2.1 Released: Includes Minor Bug Fixes and Improvements [Updated]

Apple has just released iPhone firmware 2.2.1 (5H11A) through iTunes.

The firmware update contains minor bug fixes and improvements such as improved stability of Safari and a fix for an issue where some images saved from Mail do not display correctly in the Camera Roll.

The release notes lists minor bug fixes and improvements in iPhone firmware 2.2.1. They are mentioned below:

• Improved general stability of Safari
• Fixed issue where some images saved from Mail do not display correctly in the Camera Roll

Its good to see that it includes improved stability of Safari, so hopefully it should reduce the iPhone Safari crashes further though iPhone firmware 2.2 had reduced it to some extent.
