You should have done more research before making such claims. They are all at least half wrong.

It is still possible to go to 3.1.2 via the only true safe way (staying on the pwnage train) using pwnagetool or pwnagetool custom ipsw if you don't own a mac.

There are plenty of threads about this on here. Search for one and go from there.

Stay on the pwnagetrain it is the main way to gurantee bothjailbreak and unlock will survive. Especially on the 3GS
