Actually we don't. They tell you to use the R4 trimmer because some trimmers overtrim, often messing up wifi and download play. I previously trimmed with EZ-trim and it works just fine.
Oh, i wasnt sure if the wireless in 07 was download too, i thought it was...Oh well then i change my game to Fifa 06jagviper, WTF are you talking about ? 07 got no Downloadplay, only 06 got one...
