Hi guys, need some of your expert advice on PSP.

I own an old fat PSP using 3.40 OE-A firmware. Its been good for me ever since I first installed it. No problem playing games or movies. I can play FF:CC and GoW without problem.

Only thing is, I think it would be right for me to keep current with the latest firmware. I've been away from the scene for too long, so to read back all the issues regarding previous version of firmwares is painstaking.

Can you suggest what is the best/stable firmware that I can depend on for a long time. I'm not looking into upgrading my firmwares in a weekly basis. Once a year is good for me. It would help if you guys give me a rough guide on what to do first and next. A good guide link would help too. Thx in advance.
