came in the mail today! its CFW 3.80 m33-5. so I was wrong on the version. should I upgrade to 3.90m33? or leave it as is. I heard the custom firmware can be upgraded with the wifi system upgrade thingy? I bit the bullet and got a 4gb ms. so I need game suggestions, I already have Patapon, Echochrome, SFA3, FFVII:CC and GOW.
