Check your iTunes for 2.2.1 iPhone Software Update.
If you have your iPhone jailbroken and/or unlocked, wait before updating.
iPhone 2.2.1 update needs to be tested:
1. that it can be jailbroken
2. that it can be unlocked
Our initial test did not find any new functionality.
But documentation from Apple states the following:
- Improved general stability of Safari
- Fixed issue where some images saved from Mail do not display correctly in the Camera Roll
Our full 2.2.1 review will be available shortly.
