English Firware on Japanese PSP

I have a question guys that it concerns me about future firmware updates and is related to the future value of a Japanese PSP to a US user.

If you have a Japanese PSP do you need to upgrade to a Japanese firmware when it becomes available or will you be able to use the English firmware version as well?

Thanks.

IP address on the psp will it set automatically or will u have to do it manually

it sets automaticaly....
