Still suffering from iPhone 4 proximity sensor problems? Face dialing a family member while on the phone for business? Hanging up or muting with the brush of a cheek? Macworld has a list of things that could help fix it up:
Like the clean re-install we mentioned previously, some of these seem to work for some people with the problem some of the time. Hey, it's problem solving in complete darkness, it'll be hit and miss. Macworld's "hunch" is that it's not as widespread as the antenna attenuation problem and that it's most likely a software glitch that will get fixed in the next firmware updated. That doesn't mean, however, that it won't drive afflicted users crazy in the meantime.
