I suggest you do so! Personally though, I took my time to check all the CFWs available at the moment, Rebug was the most suggested, has the most features, and is great to me so far. You can also simply switch from normal to REBUG mode, which spoofs the latest firmware and lets you access PSN (and activate games like Tokyo Jungle!)
Fix not fully work on RE Op Raccoon City on the (USA) version
privat, I tried your fix for the RE Op Raccoon City on the (USA) version, and there seems to be problem. The game starts fine, with sound and all, but it cannot quit the game. When I press pause, and exit the game, it freeze. Have to press pwr to kill it. Do you know why? (Anyone else experience it in their RE Op Raccoon City USA version?)
Also another time, weird thing happen, I was in the last room in the first stage, and all the member are in the room, but there is a message on screen saying that "all member must be in there to proceed" I ended up restart the game then it go through the 2nd time... weird.
Ya I reported here the freezing when quitting glitch back around when that fix was first issued. I believe yours is the 1st post confirming I wasn't the only person experiencing this same problem. I've since acquired the BLES version, so hopefully I won't have any more problems with this title.
