I've jailbroken my 3GS only once. I was running 3.0.1 at the time, used Redsn0w and everything has been working great. I've seen too many problems with 3.1 or 3.1.2 to update. I do have my 3.0 ECID on file with Cydia. My question is, are the iBEC and iBSS files that I read about still important for future jailbreaks? Or is Saurik's bypass-server eliminating the need for the info in those files? If they are still important, is there a way to capture the files without restoring and re-jailbreaking? I'm just trying to prepare myself for future firmware updates from Apple. I hate the idea of losing my jailbreak.
