I don't know what browser the v2.0 firmware uses, but it has to be vulnerable. I went through my network setup on my PSP and got it to the Connection TEST and left it connected (I have 1.52 firmware). Then i started running X-scan against it. This is for Network penetration testing. Interestingly I found several hits for Vuln/exploits in its network connection. Unfortunately all they were able to do is crash or reset the PSP. As i haven't upgraded to 2.0 I am not actually able to attack the Browser, But i wonder if its possible to trick the browser into running programs, or some useful exploit. I might be blowing smoke up my own ***, but was wondering if anyone else may have 2.0 and be able to try this.. Just an idea.
