Tutorial: Save your certificate (ECID) in case you want to revert to version 3.1.2

Hello iPhone users!.., THIS PROCEDURE IS FULLY COMPATIBLE WITH FUTURE FIRMWARE SUCH AS 3.1.3 AND SIMILAR.

Hi, as I mentioned in the previous post, it's no longer possible to restore firmware 3.1.2 because Apple doesn't want jailbreaking of our devices... and although it's possible for 3G models, 1st Gen iPod and 2nd Gen iPod (not the MC series), it's not possible for the rest...
