I went to the sony PSP update page and saw 2.0 is out but it said this under the PSP picture:
This update is for customers who own the PSP* (PlayStationPortable) model number PSP-1001 K. DO NOT update your PSP* system through this Web site if you own a different model of the PSP* system. There is no guarantee of proper operation with other models of the PSP* system.
I guess I am confused as to why they said this. Does it mean that if you have a US PSP you should use this and if you got a JAP PSP you shouldent update with this site??
If the above is the case sony should have made it more clear.
