Take a look at tinyCFW from tinyUmbrella - it's made specifically for those of us with an iPad2 3G. It will allow you to downgrade to 4.3.3 when at a higher iOS version. From what I've read and experiences I've seen referenced it will allow you to downgrade (assuming, of course, you have your 4.3.3 blobs saved/available). I haven't used it because I haven't yet have the need. I do have my 4.3.3 saved and the special IPSW to do the downgrade if I ever have the need.

From what I understand you will, after all is said and done after the downgrade, be running 4.3.3 under the baseband from the higher version.

Thanks for the heads up on this! It's great to know I would be able to downgrade the firmware.
 
TinyCFW is a god send!

Saved blobs through TinyUmbrella for 5.0.1

Just updated my iPad 2 3G from 4.3.3 to 5.0.1 through iTunes.

Downloaded 4.3.3 ipsw from Redmond Pie and created the custom build through TinyCFW.

Booted up Tiny Umbrella and started the server and ensured my 4.3.3 was found, then put iPad in DFU and shift restored the 4.3.3.

All in 10 minutes, quite a nifty tool!

How long did it take for you to create the custom build using TinyCFW? I was running that program for a few hours and it was stuck on that. I was able to download what it supposed to be the bbupdate file through TU website, but I am going to try again and run the program while I am at work and see what happens.

When I did it with my Mac, it only took a few minutes. There wasn't any progress indicator or notification that it was finished. Just look for the created IPSW file and see that it is about the same size as the original. I also checked the resource monitor to see that the CPU wasn't working with the program still, then just closed it down.

I'm trying it with Windows 7. I'll see how things are when I get home. Since I did download a bbupdate file from TU's website, I might go ahead and update to 5.01 and see if I can downgrade.
 
If I'm on 4.3.3 and have no blobs, I'm out of luck, right? I missed the signing window originally. I'm assuming that means there's no chance of going back if I upgrade, but I figured I may as well ask in case something magical has happened recently.

I couldn't get one built with Win7 either... I was able to get one built with osX Lion, tho. I'm glad I have both... :)

If you had an iPad1 you could use iFaith to grab the 4.3.3 blobs as long as you are currently running 4.3.3 on it. However, iFaith does not currently work with the iPad2 (which I believe you have based on your signature). I'd say you are out of luck for your device to save the 4.3.3 blobs.

Does it work with CDMA?

I was like you. I thought I didn't have them either but then I found out Cydia had mine and was able to get them. I used Tinyumbrella yesterday and saved them.

Took about 2/3 minutes running on an i7 Macbook Pro with 4GB.

The Tiny CFW programme apparently needs a minimum of 2.5GB of RAM to work.
 
A5 faq

How could pod2g have an untethered 4S and dev teams still haven't released tools to achieve this at home ?

The exploit I used to inject the untethering files to the 4S relies on having a developer account, and can't be released publicly.
It's the same reason why @MuscleNerd has an iPad 2 tethered jailbreak but couldn't distribute it.
So, we need to find a distributable exploit to remount the system partition read/write and to set Corona files at the correct places.

Why A4 version of Corona was easier to release ?

Because a tethered jailbreak is a good way to install Corona!

Why don't you do a tethered jailbreak then ?

A tethered jailbreak also relies on an exploitable vulnerability that we still haven't found yet !

pod2g, release this stuff quick, [your insult here], I've waited enough now.

If I could, I would !

Source -pod2g

So it looks like we may be waiting longer then we thought. Such a shame
 
I'm not feeling veru optimistic about about seeing a A5 jailbreak any time soon, at least after reading the following from pod2g's website:

Dude I already made a new thread before you posted this here lol?????
 
I assume this was all true before he said a week, right? So hopefully it changes nothing, and is just an explanation for why A5 took a few more weeks than A4.

I'm not sure because he release a weeks notice than said they basically have either come across a problem or had a problem? I think they jailbreak has been read for some time but like he stated only for developers not public so I'm not sure if he released this today to let us know that it will be delayed
 
Right now I am regretting updating my iPad 2 to 5.0.1 and not just because there might be a longer delay in the jailbreak. I updated late last night and when I was leaving for work this morning, I noticed I saw nothing in settings for me to enable 3G. I don't have WiFi access at work, so it looks like I will be stuck on Edge until I get home from work. Ugh! Looks like I might be testing whether TinyCFW will work for me in restoring to 4.3.3.
 
Honestly speaking, I don't think it will be long before it's released.

Remember they're looking for distributable exploit. So surely, once they've found one, coding for it to work as a public release shouldn't take long.

Then again, I'm sure it's a lot more complicated than how I've worded it.

I think that it will still be out next week if we don't see it next week then we can think otherwise
 
Latest a5 jailbreak news!!!

@planetbeing, the legendary hacker behind iPhone Linux and lot of jailbreaks (see http://theiphonewiki.com/wiki/index.php?title=User:Planetbeing) has joined the A5 research!

The famous @MuscleNerd (http://theiphonewiki.com/wiki/index.php?title=User:MuscleNerd), the leader of the iPhone Dev Team, who did a lot of tests for Corona and whom integrated it and made it simple in redsn0w is willing to help also.

And last, but not least @p0sixninja (http://theiphonewiki.com/wiki/index.php?title=User:Posixninja), the leader of the Chronic Dev Team, and my partner for years on iPhone security research has started to code and fuzz the Apple sandbox.

We now have a dream team to find a path for a public release of the A5 jailbreak.

Cross your fingers.



Looks like its here at last

I wouldn't hold your breath. Someone else has said they're looking into it with the guys who have already been workin on it for a while.
I'm looking forward to it but let's not get ahead of ourselves :(

Come on. Think about it clearly .

They are all highly experienced in the aspect so it's impossible for them to fail. If they fail this then apple has won. Never going to happen. They will all be searching for public exploit now so the speed will pick up once the public is found all the dev team has to do is pack it and check it and wolah" download time,

I see where you're coming form, but one more person isn't going to make it happen overnight. May speed it up a day or 2.

Also, it's voila not wolah. It's a pet hate of mine that lol
