i followed the steps and i did get an increase in speed, but now its up and down again. im going to mess with it more in other areas to see if it can be more consistent somewhere else.
checkout Wavezero's recommended tweaks (internet speed in post #6)

also for the people that dont have a cellular line2, i had it the other day...did a hard reset today and now its gone. actually i didnt even have cellular line either until I used opera. my wifes phone has it and we are both on stock roms and have the same tweaks.
could the cellular line2 be 1X and cellular line be EVDO?
thanks to all!
