Homebrew on PSP 1.5

[wsounitepirate895]

Might be a month late but heres some ways, 1.5 is in the Spiderman stickered box, Serial with "K" at the end, and no letter at the end.

the ones that have A, B, or so on (except K) have 1.51 and above

actually the boxes with the letter A by the serial contain a 1.5(unless you got it refurbished or something)B by the serial # contains 1.51. i havent heard anything about a K though.
