Ok, first, I don't think there are 16gb versions, other than maybe one for korea?
Second, The main issue here is the international version vs. the U.S. version, I believe there is quite a bit of difference in the firmwares of these versions, so you should probably have sections for "U.S. 4.0, U.S 5.0, International 4.0, International 5.0"
You might get more positive results that way
I am needing the 4.0 U.S Pit, btw, so thank you for creating this thread!
Edit: also, didn't you say in your other thread that heindmall doesn't work with these?
