Okay I am soooo new to this! I really don't know what's what. I was given a already jailbroken iPhone 3GS 16 GB from my boyfriend that needs to be upgraded/updated to the newest version of iOS. I currently have the version 4.0.2 (8A400). I know it has to be done by computer by someone else other than my bf, so yea Idk if that helps some. I have limera1n app and cydia app already installed on my iPhone obviously, but I don't know how to do upgrade it to the shsh's I have. On the top of my cydia it has a list of shsh: iOS 4.1, 5.0.1, 6.0.1, but as well as there is this essential upgrade option that has been popping up lately so that's why I been questioning myself can I do the complete upgrade or what can I do?? It gives me three options: Upgrade Essential, Complete Upgrade, and Ignore (Temporary). HELP ME, please.... thanks!

If your iPhone is old bootrom: back up in iTunes, restore to iOS 6.0.1, activate with original carrier sim (or any sim if factory unlocked), jailbreak with redsn0w (if applicable)

If your iPhone is new bootrom: back up in iTunes, using redsn0w: restore to iOS 5.0.1, activate via iTunes using original carrier sim (or any sim if factory unlocked), jailbreak with redsn0w (if applicable)

hope this helps!

  • old bootrom is 359.3
  • new bootrom is 359.3.2

redsn0w will tell you which yours is

Update Cydia if at your newer iOS, if not, it doesn't matter because you are going to restore anyway.
