THis is good news! Also great that Dan Andrews can donate a 2G to you. Would it be possible to scan the 2G board without the processor? I don't know if there are any exposed traces, but It would still be nice to have a picture to look at. If we could get a hold of a 3G, I think it would be a good idea to scan the traces under it's processor. I know the RAM bus is exposed on that one (just look at the pictures). We could see which pins control the RAM.
