I'm on MarcusantRomV3 and with the EC05 modem I would get similar download speeds as you on the Los Angeles server. However, I flashed the EL30 modem yesterday, and my speeds have just been cut down to 20 kb/s :/
I've always had speeds like this were I live regardless of my ROM/Setup, the tower that I connect to must be some super tower lol. My setup is CM9 Alpha 3 with all the mods from the Epic's development forum. (Scrolling, V6, 3G)
