I was thinking of downgrading my 2.00 psp, but i have the original japanese update (i was very anxious to have a portable browser). Unfortunately the browser is way too slow and the memory cache is way too small. I read a while back on this forum that there were problems downgrading this version of the 2.00 update, and this is the only thinkg stopping me from upgrading. Have all of the potential problems been fixed? I really dont want to risk bricking my psp. Thanks a lot!
