Some published reports today subjected that preforming a “Network Reset” correct some of the signal issues on the iPhone. Because it is a simple an non-destructive procedure I decided to give it a try.
Settings –> General –> Reset –> Reset Network Settings
–Click the Red Button–
–wait–
After the Reboot, the first thing I noticed was full signal strength. WOW! That’s not something I’v seen sense upgrading to iOS 4. However when I picked the phone up I lost 3 bars almost instantly. Placing the phone down, 2 bars came back quickly, but the fifth bar took a while to return.
I can repeat the 3 bar loss trick pretty consistently. Ironically when I “cup” the phone in the manner which has been demonstrated online to block signal, i actually gain a bar of signal back. 
I need to do some field testing tomorrow. (Something Apple seems to have failed to do). But at least in the near term, I feel better about signal.
