Default Posted the same in the Dream forum, but might be handy to know in this forum too :

People... the mentioned settings will only work if your network supports them!
Most important is the fact that they NEED to be set to the value that your network is currently supporting if you want to enjoy optimal speeds!!


ro.ril.hsxpa : inidcates hsxpa support of target network :

Not speed related, but still nice to have :

ro.ril.enable.3g.prefix : adds the 3G prefix to the operator name.

ro.ril.enable.dtm : Only set this to 1 if your network allows simultaneous transfer of Circuit switched (CS) voice and Packet switched (PS) data over the same radio channel (ARFCN).
