actually it was on all iphone 4 ... each ip4, when held "incorrectly" aka..naturally by any "normal" human, the signal would drop 1 or 1.5 bars. so if your signal was more than 3 bars, then it would still retain a signal with 1 bar left. but if you are on the fringe of service, .... boom you dropped a call. there are many many many reviewers and vids that prove this. from non-biased demos. solution: 1. you should hold it differently.. dont hold it like in a natural way.. do it the JOBS way! 2. here is a rubberband to cover the great metal material that we put in to show off design and beauty.. that should fix the "non-issue"
