Our friends at www.precentral.net have brought us a tip that will help us all. (And maybe, it'll work with the Hero aswell.)
By dialing ##3836# you can switch from EV-DO Rev. A, to 1xRTT or EV-DO Rev. 0.
Data speeds brought by these transistors are:
1xRTT -- 60-100 Kbps // EDGE -- 100-200 Kbps
EV-DO Rev. 0 -- up to 1.4 Mbps // HSPA+ -- 3.5 Mbps
EV-DO Rev. A -- up to 2.0 Mbps // HSPDA -- 7.2 Mbps
I myself have forced 1xRTT on my Pre, to conserve battery life. ( i hope...)
