Check iPhone 3GS BootRom (Windows, Mac)

By:

In this guide you’ll learn how to check iPhone 3GS bootrom whether its new bootrom [iBoot-359.3.2] or old bootrom [iBoot-359.3.2]. We are going to cover how to check bootrom version of iPhone 3GS in both the Windows and Mac OS X.

Why to Check BootRom?

There are two types of BootRom in iPhone 3GS. Older iPhone 3Gs comes with Old BootRom [iBoot-359.3] while the newer units of iPhone 3GS has New BootRom [iBoot-359.3.2]. Old BootRom is vulnerable to jailbreak exploit but there’s no jailbreak exploit found in New BootRom so far. So, it’s important to know your BootRom version prior to jailbreak.

iPod Touch Users

iPod Touch 3G and iPod Touch 2G users are also affected by this. However, you can confirm the jailbreak just by checking your iPod Touch model.
All iPod Touch 3G on iOS 4 cannot be jailbroken ATM.
To confirm if your iPod Touch 2G (MC) is jailbreakable or not, check the iPod Touch model. If it starts with MC then you cannot jailbreak iOS 4 on your iPod Touch 2G. Only Non-MC models are vulnerable to jailbreak exploit. You can check iPod Touch model by going to: Settings > General > About > Model

    Well I upgraded to iOS4 before reading all this, It was jailbroken before, not anymore… so just to get this straight, the procedure to get it into DFU mode also gets it out of it?

I also had no success with idetector in dfu mode, device not found. And I have no device instance path in device manager apple usb properties!

iphone 3GS with original OS 4 8A293 MC133X 05.13.04

Have tried everything and every tool to try to get this mother jb’ed again. Itunes 9.2 won’t restore on old or new pc even though I have blobs saved on saurik’s server. redsnow won’t process any of my ipsw’s.

I figure I have the new bootrom. I sure hope that blackra1n or somebody else can get a release for all phones soon.

  holde down.. home+power for 10 sec and then let go home button and keep holding power.. it should turn ur iPhone off..
  However if it’s tethered jailbroken.. you must run the tool again to go to home screen
