How do you fix a dns error for a PSP?

DNS error 80410413 means the web address was typed in wrong eg: i tryed every thing when this mesg came up, then when i nearly gave up i typed www.facebook.co.uk and it changes the address to http://en-gb.facebook.com/ the psp cant do this so it just gives an error mesg i then typed in the address on my psp the exact address; http://en-gb.facebook.com/ AND IT WORKS :) WOWO :)
