easiest way to check bootrom version

[razor1]

what is the easiest way to check your bootrom version on a 3gs? I got a refurb yesterday, but don't want the problem after shutting down everytime.

Hello

Use this software: http://downloads.ih8sn0w.com/f0recast-1.1.exe

You can look at your serial number as well. 4th and 5th digit if it is 39 and under you have the old bootrom. Anything else is the new bootrom.

What if the number is under 39 but it starts with MC?

[i.Annie]

MC models are irrelevant to iPhones and only to iPods touch

oh ok thanks so that means it's old bootrom then right?

The date of the build is just a general guideline for determining the bootrom version, you need put your phone in DFU mode to tell for sure.

Ok thanks I just used the iForecast thing
