Nobody should update unless they are getting a camera or gps for their psp. Otherwise if they really need it. But a smart word of advice, don't update until it's optional. Meaning, do not update until 3.0 is cracked and downgradeable.

EDIT:
Hey ain't that some bullshit, you gotta have 3.0 to use with the ps3? Is this true?? Man that sucks, oh well time to upgrade I guess.
