The jailbreakers have been having fun with this one. A well know and publicised security flaw in iOS which used a PDF exploit to jailbreak the iPhone has been patched by Apple. It seems the only point of iOS 4.0.2 is to fix this exploit in the iPhone. Aside from jailbreaking, it is good to see Apple respond fast to these security issues, particularly for enterprise users. There is also an update for the iPad software version 3.2.2.
