You should be able to use the old redsn0w for 4.0 on windows on your 4.1. This will jailbreak your iphone but will leave you with some issues (phone icon missing). From here you can install a custom firmware 4.0 made with pwnage tool or sn0wbreeze. Or you can wait for the windows version of the updated redsn0w to come out which will hopefully be soon.

You obviously didn't read everything I said. jailbreaking it with the old redsn0w is done just so that you can install a custom 4.0 firmware.
If you want 4.1 jailbroken now there is an unofficial pwnage tool floating around to make a custom 4.1 but not sure if it works on ppc macs.

My bad. Where do I find a custom 4.0. I'm currently on a stock 4.1

Gary, why don't you just restore to 3.1.3 and use Redsn0w 0.9.4 if you want to JB? Of course you still won't have an unlock for now.

You are on a 3G phone right?
If you'll go to my guide, you'll see that the iPhone 3G can be restored to 3.1.x without SHSHs on file. You'll also be able to JB it then, you just won't get to have an unlock since you already updated the baseband.

Thanks, I'll try that. Use the 3.1.3 that's in the download section, here? Can I then go to 4.1 when the new redsn0w for Windows is released, and hopefully unlock in the future?
Will I lose my songs when I downgrade to 3.1.3?
Annie, can you give me a link to your guide, please?

You can find the 3.1.3 ipsw here on MMi's downloads section.
You'll also want to get TinyUmbrella or Recboot. Your phone will receive error 1015 (or any variation of it) so you'll use one of those tools to kick it out of recovery mode, then you'll be fine.
Redsn0w 0.9.4 is the one you want. While you're getting the 3.1.3 ipsw, get the 3.1.2 ipsw while you're at it. You'll need the 3.1.2 ipsw for Redsn0w.
You could go the Jailbreakme route since being on a 3G phone you can use custom firmwares without worrying about JB method. Jailbreakme can be a little unstable tho, but it's up to you.
When the 4.1 JB is released, you'll likely be able to upgrade to 4.1 and JB no problem.
You will not lose your music. Just resync your phone to iTunes to get them back on. Be sure to set your phone up as new and not restore from back up. Save your contacts in Google contacts or Microsoft Outlook or Yahoo! cuz you might lose them. And back up your photos/vids too just in case.

Could I please have a link to your restore guide.
09-22-2010, 04:15 PM #53
I don't have a restore guide, yet.
I can give you the steps to doing so in a few minutes.

Annie, Thanks for the thread! Quick question: I have a 3GS (Old BR) that is on 4.0.1 jailbroken on jailbreakMe. May I use spirit2pwn to change the jailbreak for custom firmwares? Thanks!

1) shift+restore to 3.1.3 ipsw you downloaded
2) upon receiving error 1015. 1014, 1013, 1011, or 1004 use TinyUmbrella to kick out of recovery mode.
3) if you have an official carrier's SIM, activate phone. If not skip next step.
4) go to Safari then type "jailbreakme(dot)com" and slide to JB. You should be JB now.
5) with no SIM, open Redsn0w 0.9.4. Select the 3.1.2 (not 3.1.3) ipsw
6) select "Cydia"
7) follow instructions further and you should be JB.

Ok, my question is if i do shift and restore with iphone 4 and select the 4.0.1 firmware, then why, when I get an error, can't I use tiny umbrella to kick the phone out of recovery? Shouldn't this be possible?
Never mind, I finally tried it and I see why. Apple doesn't let you get past the first step.

It should be possible. Perhaps try Recboot instead. Be sure that the error you're getting is 1015, 1014, 1013, 1011, or 1004. If it isn't any of those errors, then possibly your phone isn't stuck in recovery but in DFU, which TU or Recboot does not kick it out of.
09-23-2010, 02:03 AM #58hello someone please help...once again.
Ok, I have an iphone 4 4.0.2 with shsh blobs saved.
There is a new 4.1 that is out already.
How can I jailbreak at this point?
Do i upgrade to 4.1 then downgrade to 4.0.2 then jailbreak.
This phone has never been jailbroken.
Also, my "other" memory has all of a sudden filled up...for no reason. is this a common problem with the iphone 4. Do i have to restore? It has been backed up under the 4.0.2 thus far. If i upgrade it will automatically upgrade to 4.1 as well. Do i go ahead and save a 4.0.2ipsw file for now???
I need to jailbreak this iphone and i've been trying for months yet i keep upgrading and not saving my shsh blobs...now that their saved..someone please guide me step by step in how to jailbrak.
09-23-2010, 02:50 AM #59
If you haven't saved your shsh blobs prior to 4.0.2, there is no way for you to jailbreak until the coveted 4.1 for iphone 4 is released. You're in the same boat as the rest of us.
09-23-2010, 08:10 AM #60
You need to stop upgrading and save your blobs. It doesn't take much time to do so. The first thing I did for my iP4 is save my 4.1 SHSHs for now since it came with 4.0.2.
You should also look through the guide before posting. All the questions you asked were answered in there. iP4 on 4.0.2 is a no go on JB and cannot be unless you have SHSHs to downgrade to 4.0.1.
