iphone OS3.1.3 removes cydia - Do not update it if

you have jailbroke your iphone.

Damn it, I\'ve just updated my iphone 3GS to OS3.1.3 and found the jailbreak is not working anymore. Cydia icon was removed and all hacked apps are useless now.

It is fun. I will try to break it again. Surely, iphone-dev team will have other ways to do it again for the new OS.
