What version of PSP is out RIGHT NOW?

I asked for a PSP for my birthday which is this Tuesday but I'm wondering what version of the PSP is out currently? I want to be able to use emulators like SNES9X, and all that but I keep hearing about this exploit you have to do that could corrupt your Memory Card and your PSP itself if it isn't done correctly.

Of course I don't want to ruin my shiny new PSP so if you could tell me what version I'm likely to be getting that would be a lot of help. I'll be buying a 1 GB memory card as well and hell if I'm ruining that as well. =/

Anyways if I knew what version was out right now I'd be able to know what I'll have to wait for in able to successfully use home-brew software.

Thanks a lot!
