> iOS updates are not reversible (technically it can be done, but for lambda users it's a lost cause).
I want to be clear that this is a lost cause for effectively everyone: I'm saurik, and, even with access to people like geohot and iH8Sn0w, if you give me a phone that is running a later version of the operating system and ask to downgrade, I'm going to say you need to lobby your congressperson to force Apple to allow that... the only thing that even sort of works is if you had a buggy version of the firmware to start with and did some prep work you can sometimes manage to get a downgrade to work if the firmware you upgrade to (or the bootloader itself) is also buggy... it isn't like it is "just really hard to do because it requires manual labor": it is only possible due to mistakes in Apple's attempts to make sure it can't be done.
