hi guys, i am dieing for an untethered jailbreak, and i was just wondering if i can replace my iphone 3gs's bootrom with the one in my ipod touch. are they the same size and shape? are they compatible? this information would be very much appreciated. i am probably not going to do it cuz i dont want to void the warranty or screw anything up...so its just for educational purposes. thanks in advance?
Got a tip for us?

Can i swap out the new 3gs bootrom with a 2g ipod touch bootrom?

I could be wrong, but I'm pretty sure that the bootrom is actually fixed in silicon located directly on the CPU die, not in a separate ROM chip. (Which is partly why I believe the iPhone 3G's bootrom has, to date, not been updated to patch the Pwnage bug in the S5L8900 bootrom DFU code, since it would be a hassle to produce another rev of the CPU simply to fix that hole, and is also why I was really surprised when Apple started manufacturing 3GS phones that patched out 24kpwn in the bootrom. 'cause if they bothered to do it with the 3GS, why not with newly-manufactured 3G phones, too?)
Even if that wasn't the case, the bootrom code is very closely tied to the CPU itself, so, even IF an iPod ROM chip was pin-compatible with the iPhone one, it is extremely doubtful that it would succeed in booting up the device properly.
So, no.

Why not?
Jut get a diamond saw and cut out the gates that implement the boot code on the die on the 2G. Drop a bit of solder paste on the 3GS CPU, sldide the 2G die piece into place, and solder. I recommend using a torch rather than a soldering iron, you'll get better heat distribution.
Let us know how it goes.

Is the OP the brother of Spaz?
Hey, I've got my problems with TheSpaz, but at least the guy gets most of his facts straight.
Wow 1+
I think you are on to something here. Could also be Spaz himself.

I'm undecided at this point about whether pcs_are_junk is a troll or just incredibly naïve and ignorant. If the latter, I would like to give him a chance to learn; but he really needs to stop spreading misinformation while he does his growing up.
