We here at Joystiq understand that waiting for stuff is hard; heck, we're still waiting on those Toy Story graphics (badum-ching). But you don't have to wait for Sony's official GPS module (PSP-290) if you want GPS support on your PSP, just hack it in there.
Using a PSP remote, a GPS receiver, a USB cable, and some other bric-a-brac, you'll be able to hack GPS support into your unwilling PSP. Couple that hardware with some willing software (you'll need kernel access to use theirs, so try this) and you've got yourself a fancy little package. And it only cost you $120+. Really folks, sometimes waiting is just easier.
