 Too much of their network is not upgraded or not fully upgraded and can't handle the load of a lot of data.  There are not enough cell cites with capacity for HSPDA in enough places.   Try 3g on Sprint if you have not already.  It's a uniform network built around a uniform wireless liscense.  Everywhere Sprint has a CDMA signal-they have 3g with outstanding capacity.  ATT is not even close to that yet. 

I am sure that you are right and Sprint's network is better.  I just prefer to use a GSM carrier because it allows me to swap phone easily without having to involve the carrier, etc.  Also, they work overseas.  If Verizon was GSM, I would have switched years ago.
