Okay, so I need everybodys help on this one. If you attach a cell phone to a PSP via headset output on cellphone to a custom made external input connected to a PSP. Then using Sony headset to talk from cell-phone-connected-PSP to whoever you're calling. The call would be made from the PSP using Jajah, you know the voIP software compatible on PSP. Feel free to ask any question on something you don't understand, because quite frankly, I really don't understand it. But most importantly, tell me if this can work, how it would work, and if anyone cares to have a cellphone attached to a PSP.
