Jailbreakers and unlockers: don't update to iOS 5.0.1

Apple has recently released iOS 5.0.1. It is still tethered jailbreakable. However if you want untethered jailbreak or unlock - you should stay away from 5.0.1

Earlier this week pod2g reported that a code signing bug found in iOS 5.0 will make it easier for hackers to develop a full jailbreak for iOS 5 firmware version. That bug might have been closed in iOS 5.0.1. UPDATE: According to pod2g the bug is still present, but harder to exploit because another exploit found by Charlie Miller is fixed in iOS 5.0.1.

Also, MuscleNerd via twitter has warned iOS users that there is no downgrade from iOS 5.0.1 to iOS 5.0 yet and he recommends to wait until downgrade mechanism is available.

Jailbreakers and unlockers should avoid today's 5.0.1 until a flow for downgrading to 5.0 is developed.
