What's the Difference between PSP 3001 and 3006?

(Just a little tidbit that I thought I'd share with everyone. I've been reading a lot of forums on the PSP 3000 lately and encountered a lot of questions on this.) The last digit on your PSP's model simply indicates the region where it was released/sold. This is the same for all PSP's (100X, 200X & 300X).

PSP-1000-Japan
PSP-1001-US/North America
PSP-1002-Austrila/New Zealand
PSP-1003-UK
PSP-1004-Europe
PSP-1005-Korea
PSP-1006-Hong Kong/Singapore
PSP-1007-Taiwan
PSP-1008-Russia
PSP-1009-China
