Hi, I have a couple of questions …
1) Im currently running 3.1.2 (Jailbreak version) – do i need to update to 4 (via itunes) before i run sn0wBrbeze ?
2) It says above to download the version 4 os for the 3GS … im using a 3G – can i use the ipsw downloaded via iTunes or should I use the 3GS version ?
Thanks and great work

Hi, This is slightly confusing? Why do you have to put the itunes installer in a folder when you already have it installed on my PC? Also where do you get the firmware from? I already have OS4 installed on my 3Gs?

It’s a terrifying thing to jailbreak iphone without the help of apple, just do it by yourselves. Actually, I trust in iTunes more than Cydia, which collected apps paid or free, even i will get an software of third party company on their online store, but not Cydia, if it’s an video converter I want to know who created it, ifunia or aneesoft and who can provide me after-sale service.
