So, today I learned that I can drop my iPhone 3GS from 3-4 bars down to no signal by using the iPhone 4 "Death Grip" (patent pending). I also used a friends iPhone 4 a lot today and it seemed ordinary to me. Places I don't have to worry about signal, the iPhone 4 did fine. In areas with blah for signal, it seemed just as sensitive as every iPhone I've had (including holding them weird ways so as to keep my hand away from the antenna) I'm really drawn between what to believe on the issue. No doubt the effect is true...but is this really something all that new? I'm still going to pick up my iPhone 4 when it gets in and make my own determination while using the phone in my normal day to day activities.
