YES! Solution to downgrade iOS 4.3b3 to 4.2.1

[mopar]

Try jail break ipad 4.3 first use snowbreeze . and then open cydia , see in top, shsh 4.3 or shsh 4.2.1,4.3 . , if u just have shsh 4.2.1,4.3 , thats ur ipad 100% will succes downgrade

Any work around for that if you don't have 4.2.1 shsh? can it be added to device if jailbroken?

So TU's purpose is to tell you what SHSH's you have?

its purpose is to save your SHSHs locally on your PC, and optionally serve them up to iTunes when you do a restore or update. A nice by-product is that you can find out exactly what shsh you have without being jailbroken!

Hope that helps...

No workaround. Otherwise there would be no point in Apple using them...

Oh! Okay. Got it! Thank you!

 

[graywolf]

Yep. Apple closed the shsh for 4.2.1. So as f4780y said, you can't downgrade without it.

 

[SweetPoison]

So if you didn't save them, you are screwed?

Yes. And they are specific to each device, so you can't use someone else's.

Your experience is normal. Once you start the process of saving shsh with Cydia, which you did when you jailbroke 4.2.1 and chose "make my life easier", the process of saving all SHSH becomes AUTOMATIC. Cydia will save your shsh for every new version of IOS which comes out. You dont have to request it. You dont have to have that version of IOS installed. Magic!

That's why I stayed with 4.2.1. I'm doing most of the stuff on new 4.3 on my current iOS anyways. Multitouch gestures n everything minus the nitro java safari speed increase. I wonder if Cydia has an app or tweak to enable this new scripting on 4.2.1....hmmmmm ;-)

I don't even notice a difference with the safari anyway lol! Wish I stayed 4.2.1 ....

Oh! It's automatic. I kept wondering where the "make my life easier" button was.

I've noticed a slight difference in speed in Safari.

I've noticed a slight difference in speed in Safari.

Started using atomic web browser.... Think that's faster tbh...

Someone correct me if I'm wrong, but I'm pretty sure all the alternative browsers sold in the app store, including iCab and Atomic, use the Safari engine. They all essentially all front ends / extensions to Safari.
This makes complete sense if you think about the complexities of coding a reliable rendering engine. These guys didnt just pop up and get it perfect first time.
Any speed difference would be in the interface only. Rendering should be identical.
