    I wanna check my boot rom. I don't wanna try to jailbreak it before I know if it will work or not.

    uhmmm... i might be COMPLETELY off here, but im under the impression that sbsettings cannot check your bootrom.

    isnt your bootrom the thing on the protected partition that loads before and separate from the os? So...dont you need a computer to access it?

    TBH, i have no idea where the OP is going with this, but that could be because ^ that might be wrong.

    The serial number is one way to check; if the 3rd, 4th, and 5th digits of the number are 940 or higher it more than likely has the new bootrom. If it is 939 or less you should have the old bootrom; there may be some iPhones that don't fit into that criteria so here is how to check the bootrom and know for sure what you have (no jailbreak is required):

    Copy and pasted from another thread:
    To check iBoot Rom Version on Windows
    1. Put your phone into DFU mode (hold power/home till it shuts down and release power when display goes off/continue holding home till you hear a sound on your computer)
    2. device manager > universal serial bus controllers > apple mobile device
    3. Right click on this and go to properties
    4. Click details tab and should be in one of the fields below (change the drop down box till you find iBoot information).

    On a Mac:
    Put the iPhone in DFU mode then navigate to "About this Mac". From there go to "More Info...", and select USB on the list on the left. Under the USB menu you can select "Apple Mobile Device (DFU Mode)" and that will bring up information about the iPhone. About half way down it will have the iBoot information: It will either be [iBoot-359.3] or [iBoot-359.3.2] (the 359.3.2 is the new currently unjailbreakable one). To get it out of DFU mode just hold both the home and power button until it powers back on.

    Plus I don't think there is a way to check the bootrom through sbsettings anyway (correct me if I am wrong).

    My 3GS

    My numbers are 940, I just got this 3GS 16 gig yesterday. I took it home and attempted a JB almost immediately. I kept thinking I should wait. But I didn't. This isn't my first device. Anyhow it went fine. It Jailbroke without issue, and was fine. My iBoot Version is 359.3. I guess I'm just lucky and at the tail end of the old run. Perhaps the Location of manufacture will determine what date new boot roms were used. Who knows. I'm just glad I bought when I did.

    I jailbroke it too - don't know if it was because of RC2, but I can reboot my iphone without having to be sitting infront of the computer.
