The iPhone used to have a Field Test mode which displayed decibels, and you could set that to replace the bars. I used it to write this review of the Sleek booster from Wilson.
On a pre-iOS 4.0 iPhone, you could just enter the following phone number *3001#12345#* and touch ‘Call’. Given the lack of trust regarding how bars are computed and what the 'death grip' really means to reception, this utility would really be useful.
Apple may think they are out of the woods with today's offer of a free case for iPhone 4 buyers, but if a class action suit goes forward, one outcome I would like to see is bringing back that utility, so users can see the raw data, in decibels, for themselves.
I would like to see Apple reinstate this utility.iPhone used to have a Field Test mode which displayed decibels, and you could set that to replace the bars.
