While i know that the main reason why Apple released iTunes 8.2.1 today was because of the Palm Pre's hack, are jailbroken and hacktivated iPhones/iPod touches okay with the update?
This probably shouldn't be a problem, but I want like to verify with anyone who's updated already.
iTunes update specifically says this: iTunes 8.2.1 provides a number of important bug fixes and addresses an issue with verification of Apple devices.
Update: I've read MuscleNerd's twitter and it says:
8.2.1 won't kill JB of already JB devices, but yes it complicates things
