Apple Credits comex with the Saffron exploit used in JailbreakMe
@comex has now been officially credited for discovering the IOMobileFrameBuffer vulnerability that has come to be known as "Saffron" which he used in the popular and extremely user-friendly JailbreakMe 3.0. Apple details the exploit and the ability to gain system access using this exploit on their support page that outlines the changes in iOS 4.3.4.
Apple rarely ever even acknowledges the jailbreak scene. They refuse service on jailbroken devices and quietly combat the exploits that hackers use to create jailbreaks but it isn't often that they publicly acknowledge anyone specific in the scene.
It's good to see credit being given where credit is deserved
