After the succesful FaceBook 2.0 App, the application gets its new update, to the 2.1 version. This update however isn’t a major upgrade to its previous version, but it comes with several good patches/fixes. The new Facebook App comes with improved loading times, enhanced sync times and faster inbox loading (which was a very annoying problem, at least for me).
Also, the 2.1 update comes with important crash fixes and corrected timestamps for all zones. Although it’s highly recommended to update to the new version of the Facebook App for the iPhone/iPod Touch, you need to know that the new version works only on firmware 2.2. This may be a problem for many iPhone users, due to the fact that the 2.2 firmware update on jailbreaked iPhones is a little tricky, to say the least.
