iOS 6.2 update
Unless I had a bunch of towers down or operating at reduced power on my home from work then they screwed around with the signal strength bars or did something to the LTE/4G radio. I usually have 4-5 bars except in 1 area but until I got close to home I had no more than 3 bars max. BTW This is in the Southern New Jersey area between Egg Harbor Twp and Lindenwold.
iPhone 5, iOS 6.0.2
