    Hi, I have a couple of questions …

    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 ?

    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?

  18. stonee says:

    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.
