Before the next firmware update, I thought I'd post my signal strengths and compare to others. I found that you can get actual dB readings by typing this into your dial pad: *3001#12345#* Tap the actual number to toggle between number and bars. These are the readings I got: 1-2 bars = -103 to -99 dB 3-5 bars = -93 to -77 Remember a smaller negative number is actually an increase in signal strength. And an increase of 3db (eg -103 to -100) would roughly be a doubling of signal strength or power received at the antenna. The readings I show are very rough and should be taken as an approximation. BTW, I'm one of the few or many (depending on how you look at it) that is very very happy with my toy. It's white, has no cracks and syncs in less than 5 min. Never a phone a crash, but a few apps crash. Oh, and MobileMe pushes perfectly.
