If I'm not mistaken (and some google searches for "average 3g download rate" should yield you all the info you need) you can expect something in the area of 4 to maybe 5 mbps
Big difference between gbps and mbps
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
