Not sure if this is already covered here but I remember people stating you could get to a web browser through a wifi sign in page but you can also get to the browser if you go through the new user setup and click on Facebook or Twitter. I just sent a link to Google through Facebook messages and used that to navigate. I was playing around with .TIFF file formats due to the PSP years ago utilizing executable code through .TIFF images and the first one I tried to load through FB messages gave me:
Error code: 2168-0002
This was also on firmware 4.0.1.
