pretty sure its exactly the same, would be VERY nice to have flash and java support tho. but i kinda doubt it.

and theres been websites with the link to the update since it came out. i think Kyuzo said he just went to network update on his US psp and it was there.

its fully english supported there are no side effects and you can just update it to the US version 2.0 when it comes out anyway. (which will be around the 15th i thought i read earlier)
