New way to tell firmware version by box

I was at Target yesterday and noticed that they had quite a few black PSP value packs remaining, when I saw something odd. If you look at the picture of the PSP screen on the box, you may notice that the old ones have these icons pictured in this order:

SETTINGS--PHOTO--MUSIC--VIDEO--GAME

This is the original arrangement of icons for the version 1.50, 1.51, and 1.52. The black value packs that have >2.00 installed have these icons in this order:

PHOTO--MUSIC--VIDEO--GAME--NETWORK

This is a more easier way to guarantee if it is guaranteed to be applicable for homebrew. Of course, even if you do get a version 1.52, you can always downgrade it to experience homebrew. Just remember: Network icon on box = BAD PSP!
