I did the small update to 3.0.1 to save myself from any potential SMS threat and absolutely nothing is noticably different..
 
Ugh! can I downgrade to 3.0?

Ugh! I upgraded to the latest firmware. My phone was jailbroken before. I can't use Skype now via 3G.

Can I downgrade to the previous firmware?

If so, how? Thanks

Yikes I just realize I lost Cydia as well. :( What do I need to do to get back to having cydia and all my other stuff.

Did you jailbreak again?
 
I don't get why one wouldn't upgrade to correct a security vulnerability. Exploits can become become more a risk when a patch is released. Many security vulnerabilities are known privately well before an update is released. When the update becomes public, that is when all the details are out. Hackers then take advantage of users that don't update their systems. This is the case for the majority of vulnerabilities in computer systems.
 
Doesn't really apply because other phones are also vulnerable and those phones can be used to spread the attack.

That's the explanation I got.

+1

The hacker sends it directly to the vulnerable phone. If one was to infect someone who isn't immune directly then it wouldn't matter if most people were immune, because the disease would be directly introduced to them...

Really has nothing to do with this. It's not like the SMS exploit is a virus/worm that hops from one iPhone to the next.

You are all missing the point - you aren't immune if you don't install the update, but if 99% iPhones have the update, then there's not a lot of point in spending the time to try to hack the remaining 1%.
 
yeah, but the beauty of 3.01 is that it creates what one might call "herd immunity." In medicine, that basically means that enough people are immunized against a disease, it can't really spread, so even if you personally are not immune, you're largely protected anyway. Here, if enough people upgrade to 3.01, nobody would bother to try this exploit anymore (The analogy isn't perfect, but it like the term :)). So I think those who like 3.0 can stick with it, confident that they will not fall victim to the SMS exploit.

except that a disease cant run a program to see if a person is immunized or not before deciding to attack
