This is my first post, since I tend to lurk such sites until I'm sure enough I won't blurt out stupid things :).
Here is a story of a boy called me :) :
I bought a PSP in about May, and while checking the PSP I saw it's nickname: PSP151.
Now obviously I thought it was a 1.51 PSP, right? so I figured the nickname says what your firmware number is.
So time passed, I saw 1.50 got homebrew and all, while I got pissed off that somehow I had gotten a 1.51 in May, such rotten luck etc etc.
So I lent my friend my PSP recently (best thing I ever did), when I got it back
I started looking at it's settings out of pure boredom.
So I go into the system settings- and I see system software version: 1.50
I'm like WTF? isn't nickname and version software the same?
So I look around the internet and find out the cold hard truth...I'm a moron.
Anyway, going to buy a 1GB stick today, now that there's a reason to.
And to think I was sitting on my *** for like a couple of days staright waiting for WAB and Yoshi to release the downgrader LOL.
Conclusion- Don't do drugs kids (not that I do, but it's just a good thing to know)
