So, after all that

It might be a bit faster than 3G

Provided you have enough data credit to make the extra speed worthwhile

Provided your telco isn't traffic-shaping/speed limiting

Provided whatever you're (eventually) connected to can send data fast enough

Provided your signal is strong enough

Provided there's no interference with the signal

Provided few, or no, other people are trying to use the same mobile tower

Provided your phone has enough grunt to handle that many packets/second

.. or then again, it might not.
