While this isn't something from the dev teams I feel I am forced to share it with you. Certain parts of my iPod, after upgrading to 3.0 (not saying source so don't ask) I noticed some settings were still jailbroken since I simply upgraded not restored. Things from supreme preferences are still there! Such as the custom text between the battery and signal strength. It still says "You got 0wned!" Cracked apps are still there as well, though they can't be opened since there older versions.
