Last night Apple released iOS 5.0.1 for iOS app developers solving battery life problems and implementing other subtle changes in the operating system. The new version of iOS 5 has the same vulnerability exploited by limera1n so that the current version of redsn0w can jailbreak without problems, according to MuscleNerd. Unfortunately, redsn0w does not recognize the new iOS 5.0.1, so in order to jailbreak without problems, you must select the ipsw for iOS 5 using the redsn0w interface and then you will be able to jailbreak without problems.
If you have iOS 5.0.1 installed on your terminal, you can jailbreak using this tutorial but selecting iOS 5 in step 2.
