[viperdink]

here in philadelphia, pa, metro has Two Different SID numbers.I know they are to acess Tower systems. I can Change the "HOME SID" in qpst settings. How can I find out more on the towers and the system owners. YEA I GOOGLED IT! The sid numbers are 6545 and 6503.
i just want to try getting better 1x out of metro or at least choose the best signal/system i can use for me without a lot of trial and error.

This Phone is on 236 stock rom , totally rooted, all working

thanks
