Jailbreak/Unlock to latest version - Where to begin?

[stevedawg85]

I bought a 3G iPhone and am using it with Tmobile w/ a turbosim since December. If I remember correctly, January may have been the last time I updated it...I have been out of the scene since then.

I have firmware 2.1 (5F136) carrier 2.6. How can I get from this to the most latest/jailbroken/unlocked version

1.Restore device(If you want it to be fast and better battery life)
2.DFU Mode to update to the Newest 3.0.1(.1 is for a security fix)
3.Jailbreak with Redsn0w
4.Get iPhone set up and connect with wifi
5.Install Ultra Sn0w from Cydia(Should be in favorites)

SWEET!! Just what I was looking for. This should point me in the right direction. I'll follow other tuts and see how far I can get .

point redsnow at a 3.0 firmware (of the appropriate phone of course). (you'll have to download one if you don't have it, be sure to not use safari)

I'm in the same boat as the thread starter. I unlocked my 3g using yellowsnow, back when it first came out.

Now, all I have to do is download the update from itunes, update my phone, then run redsnow?

It just seems a little scary and I'd like to verify first, I remember when yellowsnow came out, if you upgraded to the wrong version your baseband was un-unlockable!

^ you'll be fine, ultrasn0w will unlock it after the jailbreak. No worries.

[sam.c]

Great. Thanked.

Ugh. Like I said, it's been a while. I updated to 3.0.1 via iTunes, and now I've got redsnow open. It's asking for the IPSW. Where can I download this ipsw as a separate file?

[blkcadi]

Try here.

or here.

Thanks. I've got the redsnow downloaded already, and I am now searching for the .ispw file that redsnow requires.

I've got the redsnow application open, and it's asking for the corresponding ISPW file, and the ISPW is what I do not have.

[blkcadi]

This will have everything you need.

[stevedawg85]

Let me make sure I have this straight... What I'm doing is basically a normal jailbreak with redsn0w (good link btw, thanks!)....
Once that is up and running, I install Ultrasn0w via the Cydia Store and this is the prog/app that actually unlocks the phone to be used with T-Mobile?
