First I thought it was cute that the above signature has "evdo rev a" listed even though he clearly has a rev 0 device. (no rev a handset is available on the market.)
Anyway. I'm in the cleveland market and My phone tests at about 260kb/s. So.. I really dont know what your doing that its that slow. I have found if you dont have very much storage memory it slows down considerably.
For the record at full speed sprint IS faster that cable. But we all know that means your the only user on the network and you live half way up a cell tower.
For the record rev a will not change much
you will notice a slight increase in download speeds but upload it where the change is going to be made.
