I'm running CM7 on MT, stock VM 61007 PRL, in zip code 55417 usually, (home and work), or nearby, (central Minneapolis, MN), and normally have adequate signal, ... until a few days ago. Now, it's weird. I have signal, turn on 3G data, ... no signal. Have signal, dial a call, suddenly no signal. "Searching for service" It's never searched here before... It's like I'm on a tower and when I ask to use it, I get kicked off. I tried investigating using OpenSignalMaps. It shows towers on the web site I can't see on my phone app. (Looking at OpenSignal - Crowd-sourced Cellular Coverage Maps for the world. I don't see the one nearest me, ever.) Is there a way to see which towers near me I could connect to, and which are in my PRL? Am I on the right track looking at towers? I contacted support, but they just said try a battery pull and I'm not convicted they'll ever help me.
