You may already know if you’ve launched iTunes recently, that Apple has released a new iPhone System Software Update 2.0.1. This update is just a bug fix patch and gives no new features. Always when a brand new update is released, if you are using an unlocked or jailbroken iPhone it is recommended that you ignore the update until different dev groups have time to update their tools.
