Yes, it does.  I'm aware of that.

I'm also aware that in the US, (you non-US people don't have all these features, 
or actually, lack of), some ISPs have been cutting back on what early ISP 
delivered, such as news, DNS, and such.  It's already been mentioned that the US 
has some of the worse internet services.

Now, I'm not sure, but perhaps Verizon Wireless doesn't provide DNS services. 
I'm also pretty sure they do not provide news.
