Well, I've given up on Cingular and am now a Verizon customer. Where before I got 0 bars, I now get four, and since that place is my apartment, I'm pretty happy with that. I even get a bar or two in my office.
I just spent the last thirty minutes or so punching numbers into my phone. It recently occurred to me that I probably could have moved all of the numbers from my previous phone onto the SIM card and just moved that over, but oh well. Next time, I suppose.
