I am thinking of buying a PSP system, now from what i've read it will come with 1.50 version on it, now its gonna want me to upgrade to 2.0 correct? I have a lynksys wireless router that i hook my laptop up with, will my psp be able to find this and logon instantly? once I have 2.0 will i be unable to run any of the old files? If the downgrader falls through will I regret upgrading? Thanks for answering these questions guys, even if they've been asked a million times.
