How to Check the Bootrom or non-MC for 3GS or ipt2G.

What??? Don't know what it means?? let me break it down for you...

When Apple created the iPhone3GS the Bootrom was the same as iPhone3G thus able to jailbreak with the same exploit as the other iDevices, then came the new shipment of iPhone3GS with new Bootrom (iBoot-359.3.2) which gives the jailbreak community headaches..

As for the iPodtouch2G, same story... So, the important part here is to be able to tell the difference with the older model and the newer (more challenging) model.

iPodtouch2G: How to check?
Good: MBxxxxx; Bad: MCxxxxx

Settings->General->About->Model: MCxxxxx or MBxxxxx?

This is how you compare MC or non-MC model for the iPodtouch2G.

iPhone3GS: How to check?

Method 1:
You can determine your production week from the Serial number in your Setting->General->About screen.

The week number is usually the 4th and 5th digit of the serial number. eg. a SN beginning with 88926xxxxxx would be week 26 of 2009.

3Gs units made week 45 or later usually have the Newer bootrom. Before week 40 they usually have the Older one. Between weeks 40 and 45, results vary, use Method 2.

Method 2:
Good: iBoot-359.3; Bad: iBoot-359.3.2

Put your iPhone into DFU mode. (iClarified)

Using Windows:

• Go to Start->Control Panel->System->Hardware->Device Manager on your Windows machine.


• Look for 'Universal Serial Bus (USB) Controller', you will find 'Apple Mobile Device USB Driver' as a subitem there.


• Right Click and choose 'Properties', navigate to 'Details' tab and select Device Instance Path from the dropdown list box. At the end of this information string, you will find the bootrom version, eg. [iBoot-359.x].

Using Mac:

• Open System Profiler and navigate to Hardware->USB in the left menu.


• In the USB Device Tree pane at top right, click on 'Apple Mobile Device (DFU Mode).'


• In the information pane at bottom right, locate the 'Serial Number' string. At the end of this information string, you will find the bootrom version, eg. ;iBoot-359.x].

After checking, remember to Hold Power + Home Button till the Apple logo appears.
