Hey, I asked the same question
here awhile ago after picking up a 1.72 destiny console and was told I could use a proxy to make the systems help page redirect to the web instead of sonys website for the manual.
I tried for a little bit just fumbling around with charles proxy and got it redirecting to google so its possible, I just didn't have the time to figure out the whole process.
I wouldn't update to 2.03 yet in case something gets discovered that needs a pre 2.0 firmware. Once something is released I'm sure someone will write up a guide to getting around the psn account requirement to use the browser or whatever ends up being used for the exploit.
