iphone4 4.0.1 which jailbreak?

[vix2000]

I have a jailbroken iphone 4 still on 4.0.1, and am thinking it needs updating. What os can I update it to that is still jailbreakable, and whats the best one? On cydia it says I have SHSH ios 4.0.1 4.0.2 4.1 4.2.1 4.2b3 if that helps. Thanks

I would suggest 4.1 as it will be untethered, plus there are multiple jailbreaks to pick from.

x98car,
I've been having this same problem, i used the pdf exploit to jailbreak, forever ago obviously, but now my cydia takes about 5 minutes to load changes and my friend who has 4.1's takes like 2 seconds.
When i try updating to 4.1 it says it can't update to 4.1.

Just throwing that out there.

Do you have 4.1 SHSH?

Do you have 4.1 SHSH?

Yes sir, all the SHSH blobs are saved in cydia.

Thanks for the replies. This is why I want to upgrade, I'm getting a few bugs and its sooooo slow!!! So do I update first? I have never done it from shsh before, is it easy? I've done a few different jailbreaks before, pwn, redsnow, spirit, any opinions on which is the best of the current bunch? I have access to both windows 7 and osx 10.6.6

Its pretty easy. Just use tiny umbrella. Make sure your SHSH are saved, start the tss server, then shift/option (depending on windows or mac) restore to 4.1 (download that manually).

Then you can use limera1n/greenpoison/redsnow 0.9.6rc8 to jailbreak. I prefer redsnow because it installs the newer, faster version of cydia.

Is there no way to do it without restoring?

[Simon]

You may be able to shift/option update but it will still wipe all your jailbreak stuff. Forgot to mention, you will get a 1004 error near the end of the restore, it is normal. Just use tiny umbrella to exit recovery when you do.

I did it and tried to simply update and it said error 21

You may need to do a dfu restore to 4.1 then. Just do a backup in itunes first then you can just restore everything after.

Thanks, its on 4.1 so now the jailbreak!!!!!

[Simon]

Like I said I prefer redsnow, the other two are more straightforward to use though.

Thanks for all your help, got redsn0w on now, very painless. Finding it a bit difficult to dl stuff from cydia compared to before but I've probably not downloaded everything I need to. All i ticked in the jb was cydia.

Now my daughter wants me to jb her 3gs which is on 4.0. Can I update this to 4.1 and then do redsn0w?

[Simon]

If hers has 4.1 shsh then ya you can. Use a custom firmware if it is unlocked and you want it to stay that way.
