    Before the number 28 in the serial is a number 9. I saw in a thread that with that you can tell if you have a new or old bootrom. What bootrom do I have?

    If you want to guess, give us the 4th, 5th, and 6th serial numbers.

    If you have a Mac, put your device into DFU. Go to System Profiler and go to Apple Device (DFU Mode). Look at the iBoot. If it ends in .3, you have the new bootrom.
