You can get various data plans from the carriers.  The more you pay, the 
more you can use, though prices in Canada are high, compared to 
elsewhere (yeah, so what else is new).  I haven't experienced any 
blocked ports and can tether my notebook or tablet to my phone for 
access to the Internet.  What do you mean by proxy in this context? One 
thing Rogers does is provide RFC1918 addresses to cell phone users.  
This should change when they make IPv6 available.

There are different standards as a result of evolution.  With 2G phones 
(GSM etc.) their was only limited bandwidth available, as the data had 
to be carried over standard GSM channels.  Then came 3G phones, which 
use a couple of generations of HSPA.  Now with LTE, there are some, but 
not all of the 4G features, including greater bandwidth and lower 
latency.  As for compatibility, I have a Google Nexus One, which runs 
HSPA & UTMS, but can fall back to GSM. The same phone will work on Bell 
& Telus, but without fall back to their old CDMA network.  LTE phones 
will fall back to HSPA etc.
