I also seem to recall reading somewhere a while back that the signal strength displayed on the iPhone was rather "optimistic," so to speak. I'd agree with mio_BB - testing is the only way to know for certain. Is there even a standard for how the signal strength is displayed? If no, then that would lead me to think the phone's maker, or the OS maker, could show you whatever they wanted to show you.
Yes, I'm a cynic. :wink:
