Cell phone data speeds with different bands?

I have done some checking, but I have not been able to find any decent info.

My current phone uses GPRS. I find that my data speeds are like slow-ish dialup. If I had to guess a comparison I’d guess around a 19.2 connection.

A phone I am looking at is a 3G (G3? Stupid one-tab browser). What kind of speed difference am I looking at in this situation? What is the supposed speed, and what is the actual speed?

3G can be a whole bunch of things, but if you’re in the US it is most likely UMTS 3G which is a high speed standard with a medium speed implementation (theoretical maximum of 14 mbit/s, and practically implemented up to 384 kbit/s). The faster substandard that allows higher throughput called HSDPA has the following status in US according to Wikipedia :

i have a a900 from sprint. connected to my laptop here are some results on some speed tests i just ran:

the best part about it is that all i pay is the $15 power vision basic package that allows unlimited data on my phone.
