No Bootrom info listed in Device Instance ID for 3GS?

[flatlined#IM]

I was checking for my Bootrom in in Device Instance ID and it was not listed there. I remember doing it a while ago and having the old bootrom. Anybody know why it would not be listed? Would still have the old bootrom do those change also with iOS Updates?

Thanks

Bootrom doesn't change.
