What's a "blob"?
As I have not yet crossed paths with this term, would somebody enlighten me as it refers to the process of downgrading an iOS? Please?
I am considering the jump from a jailbroken 5.1.1 to the just released 6.0. DoNotDisturb and the new maps with turn-byturn are the primary attractions. I would be losing, primarily, LockInfo and BiteSMS, which are pretty big losses. I am will to risk a few days of 6.0 to see if it is worth it, but want the option to downgrade and rejailbreak my device if needed. Looking at some of the posts about downgrading, the term backing up your blobs keeps popping up, but nowhere can I find what a blob is.
Thanks in advance, and be gentle please. :o

I'll leave it to the JB community to fill in the fine details...
Basically it's the digital signature that Apple issues to authenticate an iOS installation. Apple has to authenticate each installation for security reasons... and when they release a new iOS version, they typically stop "signing" or issuing the digital authentication for previous versions within a few days. It keeps people from going back to older versions of iOS.

OK - thanks for the info.
I just got a look at the iOS6 DoNotDisturb feature on a friends 4s after he did the upgrade. No thanks. Evidently it allows phone calls only through, no SMS. That is a deal killer for me. I have a 17 and 19 year old that I am pretty sure have forgotten how to make a phone call, but can type with their thumbs faster than I can think!

If you need anymore help or guidance with this, then shout back here. Myself and a few other members have completed this process many times.

Thanks all for the info. I have personally decided that the upgrade is not worth the cost of whatI will lose from my jailbreak. And, in reference to 1982ollie's post, since I have a 4S with an A5 processor, I guess this it is a moot topic to begin with.
