Unlocking iPhone 3G & 3GS official support thread (Updated 11/28/10)

^ Okay, I'm feeling really slow now. Where do I download that IPSW at? I found the one linked in the dev blog, but can't find the one that you reference. I'm totally sorry for being such a noob at this.

Don't be sorry at all. I just googled it and many sites have a link to the apple servers for download. But be sure to get the 3G 4.1 IPSW. I would go ahead and get the iPad IPSW that redsn0w is going to use also. But I haven't done this yet so sorry I can't help beyond this step. Post what happens if you're doing this now.

Okay, I got the IPSW for the phone. Now for the ipad one, is that the link that's provided on the dev blog page? I just copy/pasted the instructions since I can't link yet. The link is on step #4. Weeeee I'm so close now! I have to leave for work soon, but will be getting back on this after I get home this evening.

This one:

SIMPLIFIED ROUTE #2 (PwnageTool for OSX):

1. Read and fully understand the warning below.
2. If you have an old-bootrom 3GS and are already unlockable but want to get to 4.2.1, please wait til we release an ?unofficial? bundle for you. Read no further.
3. Read update #1 for an updated 3GS bundle.
4. Download this IPSW <------ is this the ipad one that I should download?
5. Run PwnageTool to create a custom 4.1 IPSW. Tell it you want to use the iPad baseband you just downloaded. Restore to this custom IPSW.
6. Install ultrasn0w through Cydia
7. Enjoy!

I just assumed that it wasn't for windows. Thanks for your help! I think if I can just get all the stuff downloaded, I'll be okay and figure it out as I go. I mean, it doesn't really sound hard, just a little confusing.

Any issues with your GPS? Read that many lost this ability.

Okay, I think I've got the right ipad one: iPad1,1_3.2.2_7B500_Restore.ipsw. That's correct, isn't it? So now I just open the iPad one, the iPhone one that was stated earlier (iPhone1,2_4.1_8B117_Restore,ipsw), and then redsn0w?

I think that sounds right, but I'm suffering from information overload, lol.

Okay, done! I downloaded redsn0w, and my current .ipsw to my desktop. Ran redsn0w, checked "install cydia" and "install ipad baseband". redsn0w did it's thing and then I put my SIM card in. Opened cydia, searched for ultrasn0w, ran it, rebooted, and I'm unlocked.

That's great. Any issues with battery life, or GPS? Did you use an ATT sim card at any time?

 

[foodd]

I had the ATT sim in the phone for the jailbreak. After that was done, I put in my own sim and then unlocked it. I'm really not sure if I actually needed the ATT sim, but I figured I might as well keep it in there until it was JB'd. No issues so far w/ battery life. I don't use GPS as I don't travel out of town too often.

5.15.04 baseband is not unlockable

 

[Nehemoth]

OMG, So which are my options now?

 

[Supra1jz]

well some user have been using the ipad 3.2.2 with the baseband 6.15 and that is how they are unlocking there phone but if i was you unless you really have to i would wait cause once you do it theres not going back you can not downgrade so its a big risk so read around the forum and you will see its posted everywhere..

Exactly I don't wanna do that.

BUT I don't understand why this happened.

The supposition was that after the update I could do the Unlock cause I have the old bootrom and all that stuff.

Thank you man but I had read that link several times

If you have an old-bootrom 3GS and are already unlockable but want to get to 4.2.1, please wait til we release an ?unofficial? bundle for you. Read no further.

Now I understood the Read no further. Sadly I continue reading and I read this too

If you have an iPhone3GS with an old bootrom, use redsn0w for an untethered 4.2.1 jailbreak..

But of course the beginning of that sentence is

This PwnageTool also contains...

So that reference was only valid for people using PwnageTool.

I'm guessing that I can back to 3.1.2 since when I tried to use Sn0wbreze for 4.1 update I got error 1600. Should I go back to 3.1.2 or should I wait for the "unofficial? bundle???

Best regards

 

[Nehemoth]

By The way, Why a friend of mind could unlocked his 3Gs with 4.2.1??

 

[Supra1jz]

you already updated your baseband you cannot go down on baseband so even if you go back to 3.1.2 your baseband will stay the same..

 

[Nehemoth]

You see I didn't know that cause I read several months ago, when 4.0 or 4.1 was released, that you could back to the previous baseband [with a trick?] but it looks like was that version only.

I can see that with PwnageTool you can build a custom IPSW which let you update Preserving your baseband, So why these cooked IPSW aren't released to the public? [Apple Lawyers?].

Lets hope soon we get an update cause I only use my iPhone to navigate when on the move, so WiFi is nothing to me.

Thank you for the support
