I have an I Phone 3 GS with 4.3.1 version. It was locked by AT&T when I bought it then the seller jailbroke it.

Now I want to upgrade it but I don't want AT&T to catch me. Can someone help me first how to back up my device (I have Cydia too) then upgrade and lasty, jailbreak again? Also which version can I upgrade?

Thanks for your help!!

LOL. Why are you so worried about at&t? Open cydia, on home page top part in green, what shsh do you have? Also what is the 1st 5 characters of the serial number?

(18 Jan '13, 05:03) justinred ♦ justinred's gravatar image

It is written like SHSH: IOS 4.1, 4.2.1r1, 4.3.1, 4.3.3, 6.0.1 First 5 characters of Serial Number: 80937

The other information at the end of Cydia home page; IPhone 3GS, IOS 4.3.1, Cydia 1.1.6 4085b183f329b18539c2bde9f88...... and so on...

Thank you for your help...

Connect to latest iTunes and click restore. It will restore to 6.0.1. To jailbreak, use redsn0w 9.15b3/extras/select ipsw/browse for predownloaded 6.0 ipsw then redsn0w/jailbreak/install cydia.

Any information ?

Back up in itunes and restore from backup after firmware restore. Look above and you will see "Start here: How do I jailbreak my device on iOS 5.1.1 or iOS 6.0/6.0.1? "

I tried but it didn't work :(

Now, my version is 6.0.1 and I couldn't install Cydia :( I have also another problem. My phone was locked by AT&T as I mentioned in above message. Now, it says that your phone is locked, and I can't use my Sim Card (Turkcell, in Turkey)

Jailbreak to bypass activation. Look up and read " Start here: How do I jailbreak my device on iOS 5.1.1 or iOS 6.0/6.0.1? How do I carrier unlock my iPhone?"

(21 Jan '13, 09:22) justinred ♦ justinred's gravatar image

I added Cydia too but the problem is with Carrier. It says No Network :( Please help me with that to use my own Carrier, Turkcell... My phone was off all day long, I need it :((

(21 Jan '13, 09:25) Chotanaq Chotanaq's gravatar image

Did you read the above link in How do I carrier unlock my iPhone?

(21 Jan '13, 09:29) justinred ♦ justinred's gravatar image

Yes I read it...
This message is appearing at last stage:

The SIM card inserted in this iPhone does not appear to be supported. This iPhone is not currently setup to work with carrier you're attempting to use. Please insert another SIM card from a supported carrier or request that this iPhone be unlocked.

In redsn0w, install ipad baseband, once done, do downgrade baseband. Select 6.0 ipsw before each step. Install ultrasn0w and ultrasn0w fixer from cydia to unlock.

Thank you dude!! I did it.. but I have to boot it whenever my phone is off since the jailbreak is tethered... I hope untethered version comes soon... Thanks again :)
