Will jailbreaking come to an end?

Will jailbreaking come to an end? Recently there was a post on the Dev Team blog saying

It looks like Apple is about to aggressively combat the “replay attacks†that have until now allowed users to use iTunes to restore to previous firmware versions using saved SHSH blobs.

I was just wondering if this will ever happen to jailbreaking.

This will not stop jailbreaking. They are just saying that when iOS 5 comes out, the over the air updates will not require shsh blobs so when you update, like it or not, you are updated. There is no way of going back.

So say a jailbreak is released, and apple sends out an OTA update to patch it. Anyone who updates, lost the chance to jailbreak. But everyone else who stayed at that certain software version will be able to jailbreak.

Long story short, since iTunes is no longer required, shsh blobs aren't either. Jailbreaking will live on.

So are you saying that no matter how Apple create their iOS's for the years to come, there definitely will be a hole for developers to exploit?

That's not quite right Wolfie. SHSH blobs are still there, retrieved over the air from Apple like always. iTunes was only ever the middle-man, and remember, folks will still use iTunes. OTA is just another option.
And the new blobs are even harder (ATM impossible) to bypass, because the system has been updated to bring it into line with baseband signing. So, from Apple's perspective SHSH blobs are very much required. It is a cornerstone of their IOS update security.
From a jailbreakers perspective they will no longer be worth saving (as things stand) from iOS5 since they cannot be replayed any more...

Nothing is definite, but in the millions of lines of code which make up every IOS release, there are always bugs. The code written by human beings so will always be fallible. The question is, can jailbreakers keep finding useful exploits for those bugs before Apple patches them? Probably, yes. But will it be getting any easier? Probably no...

I just hope apple doesn’t start automatic updates in the near future without the chance to say no!

That kind of thing tends to go against what most folks think of as acceptable terms of service, plus the carriers don't like it either. You can't put a 150MB update down the pipe to someone automatically if it would blow their data plan. Same with broadband services. Some parts of the world are still on very slow connections with very little data allowance, so an update may take 1 months allowance.
IMHO it will always be a choice which you must accept.

I could easily see a test case at court about this soon, would not surprise me at all if companies try this. Thing is like mentioned by someone above, for jail breaking someone will always find a way around.

Well shsh blobs as we know it are over.
