upgraded to 4.3, my mistake:(, just learned about JB a little late, can i go back?

i've jailbroken my cousin's iPhone 3Gs the other day and i realized that it has a lot of useful things to offer like for example the SBSettings. this is the most useful app/extension i think and would really love to have it.

i own an iPhone 4 but updated it when 4.3 was released. i wish i didnt do that.

since there's no JB for 4.3 yet, is there a way for me to go back to 4.2.1 so i can use the recent untethered JB for 4.2.1? Please remember i have just learned about jailbreaking the other day. so i have no idea about the importance of saving SHSH/blobs, etc..

Unfortunately you can't downgrade without SHSH blobs because Apple has stopped "signing" 4.2.1.

If you just learned about jailbreaking the other day, chances are that you didn't save your blobs with a program called Tiny Umbrella.

Short explanation= no you can't downgrade.

But on the bright side, it MAY be a matter of days before the untethered 4.3 JailBreak comes out...

So you'll have to wait.
