I made this mirror list a while ago if it can help anyone: http://ps3open.co.cc/archive/Firmwar...iL-FW-LiST.php
(maybe only MU links still works btw)
They are taken from here : PS3 Downloads - PS3 Firmware Updates
and still helpful for MD5 check: http://eurasia.nu/wiki/index.php/Ps3OsRels
But re-uploaded on multiupload...
I could add more if anyone is interested
On another note:
i also like that site for explaining more details about FW's hidden features:
sad that is not up to date though...
