Hello,

I can't figure what what Bootrom an iPhone 3Gs is running.

When in DFU mode, here's what system profiler says : iBoot-359.3

The model number starts with MC

The serial number's first 5 characters : 5K111

f0recast answers NO for Untethered?

This iPhone was Jailbroken in order to be unlocked so it has iPad BB 06.15.00

I'm trying to downgrade it to BB 05.13.04

Thanks a lot

That's a new bootrom because it was made in 2011. The old bootrom was only made for a few months in 2009.

I agree, both the serial number and the MC in the model number indicate that it's a new bootrom but i read that iBoot-359.3 means it an old bootrom.

that's why i'm confused

The MB/MC model does not mean anything for a 3Gs. I have an old bootrom MC model and have seen new bootrom MB models.

According to iDetector, the iPhone contains Old Bootrom ..

So on one hand :
iDetector & System profiler [iBoot-359.3] = Old Bootrom

On the other :
Model number and Serial number = New Bootrom

Is this crazy or what ?

It is possible that the iPhone is a refurbished one that was given a new serial number.
