iPhone firmware 1.1.2 thwarts TIFF exploit

Apple has release iPhone firmware 1.1.2 in an attempt to close the TIFF exploit which could be used to jailbreak and hack iPhones running firmware 1.1.1. The TIFF exploit is best implemented at JailbreakMe.com which allows you to jailbreak and hack an iPhone or iPod touch, add Installer.app, fix YouTube, then repair Safari's TIFF exploit hole so that the exploit loophole is closed–right from the device itself.

Has anyone discovered any new features in 1.1.2 other than fixing the TIFF exploit hole?
