You just flash it with the USB cable that came with the phone. Only takes a couple of minutes. Apparently this is a non-branded version of the firmware before ATT got hold of it and made changes - disabled some things. This also enables tri-band and SMS.

There was a link on the web somewhere where you could download it then they were forced to take the link down I think. If you post me your email on this site, I'll contact you direct.

For your other question, I just create favorites within explorer to go to the other sites.
