After Anandtech's beautiful breakdown of the iPhone antenna and signal issues here: http://www.anandtech.com/show/3794/the-iphone-4-review/2
I decided that this might be helpful as traditionally bars don't mean crap squat. Some phones allow you to make calls at 0 bars. Others barf at 0 bars and won't function at anything fewer than 2 bars. In the end your SNR is what matters and numbers tells the real story.
Example:
Model: Motorola Milestone (GSM Droid)
Network: AT&T 3G HSDPA (be sure to indicate 2G or 3G)
Observations:
1 bar: -109dB and lower
2 bars: -99dB and lower
3 bars: -97dB to -85dB
4 bars: -79dB and higher
Edit: I'm gonna run around. I did these tests at my desk at work and this morning at breakfast. I can't seem to get that 3-4 bar transition. It happened better at home. I'm getting 85+ at work, so I need to go outdoors or something...
