Post if you have any issues but just follow the steps in the video and you will be fine.
Oh DONT select activate phone, you need an AT&T sim to activate with itunes. It doesnt have to be activated just has to be the sim. I didnt watch the video but im sure it will help walk you through it.

iPod, iPhone and iPad Firmware Download
Go to iPhone and select your model (3GS) on 3.1.3 from the list.
If you're on a Mac, you can just use Pwnagetool to create custom firmware to upgrade straight to 4.1.

After d/l 3.1.3 then just use shift restore? or wat tool do I have to use to restore ?

Download sn0wbreeze. Open it up, cook up a custom 3.1.3 firmware in there. After the custom firmware is created, shift + restore to it in iTunes.

Ok , Done that then how do I upgrade to 4.1 and unlock ?

You use Sn0wbreeze 2.0.2 to create a 4.1 custom fw and restore to that.
Unlock with Ultrasn0w in Cydia.

I'll do this weekend. just want to get all the info. needed so I can work on this upgrade. So all the MMS, SMS , youtube, Edge and tethering will work on 4.1 customs with unlocked?

Will you be hacktivating? Or do you have an AT&T SIM to activate with iTunes?
If you don't have a SIM to activate with, and you have to activate with Sn0wbreeze, you might run into some problems with YouTube and/or push. YouTube problem can be fixed with fixes from Cydia. Push is currently not fixable on 4.1. Other problems may occur, but those are the most common. Best to have an AT&T SIM. if you dont, its ok, just wanted you to know there are possible problems that might occur.

I have an AT&T SIM but no longer use AT&T so I don't know if I can use the SIM or not or I have to have a SIM with current AT&T account ?
10-22-2010, 01:35 PM #12
That SIM is fine. Doesn't have to be active.

Try another computer? Or close off all your background programs like antivirus and messengers and try again.

By deselecting "activate" in Sn0wbreeze, you will avoid YouTube and push problems. This will also, after you restore to the custom fw, not hacktivate which means it will take you to the emergency call screen. That's when you put your SIM in and plug into iTunes, and iTunes will activate your phone. This will bypass the emergency call screen and allow you to access your jb phone.

You meant when I use sn0wbreeze to create custom 4.1 OS, click "no" on activate then create the file and restore it? After that insert the AT&T SiM and launch itune to activate then use Ultrasn0w to unlock ?

Can I use sn0wbreeze 2.0.2 to create custom ipws 3.1.3 ? or I have to use sn0wbreeze 1.4. And when create 3.1.3, Do I have to choose NO on "activate" ?
10-23-2010, 02:27 PM #20
2.0.2 is only for 4.1. If you want a 3.1.x custom fw you'll have to use the version made for 3.1.x.
