Old or New Boot Rom ?

**area51crypto** · 03-01-2010, 06:56 PM

Hello,

I would like somebody who knows how to tell the old boot rom from the new boot rom on 3gs!

I have read that if the model number starts with MC its the new boot rom!

I have also read it the 4 and 5 digits on the Serial number are 40 and below it is the old boot rom!

My Iphone's model starts with MC and the 4 and 5 digits are 35 so my question is my phone old or new boot rom?

I am currently at 3.1.2 jailbroken and not tethered as I can turn off and on all day long and never have to hook it to a computer and everything is working!

Thanks

If you can turn it on and off without having to connect to the computer to start you have the old bootrom.

I bet your serial looks something like this XX006XXXXX right? If so, that means it was made like 2 or 3 weeks ago. Definitely the new bootrom, and definitely not able to be jailbroken since it's sitting at official 3.1.3

BTW, from what I have read, the MC model number doesn't mean anything in the 3G[S] world, only the 8GB iPod Touch "2G"

You're correct, I have a 3GS, model number MB715 and I have the new bootrom. And yes, my serial looks a lot like that :P

The MC thing is actually a widespread misconception. It can't actually be used to determine anything with regards to the 3GS phone.

You have the new bootrom. Serial digits 4-5 are over 40. Probably should wait to update.
