Call Of Duty: MW3 v1.21 Update Signed for v4.0 now patched for CFW usage
First the Uncharted 3: GOTY edition was patched, which was no big deal as all the included patches are still signed with the leaked v3.60 keys.
But now suprize suprize, the latest COD: MW3 update has appeared, which is rumored to be signed using the v4.0 SDK system, which means maybe a flood of new eboots will be appearing soon now.
Also for those using F*uckPSN and the latest patches, you can go online and hunt down a few friends or enemys now on the COD map of your choice, of course until Sony decides to pull the plug on the new PSN passphrase that was recently leaked, allowing those with Jailbroken CFW v3.55 consoles to get back online!
For those wondering, Activision encrypted the v1.21 update with version 4.00
I checked and this fix works on a EUR version of the game (install official patch 1.21 for EUR version of game and fix for the USA version of game (in PARAM.SFO edit only version firmware on 3.55, or install spoof(spoof does not work on DEX firmware )) and play online.
