How long is it taking to get the replacement phones? I bought mine the 2nd day it was out and my coworker bought his a couple months ago. His reception blows mine out of the water. At my house his was steady 3 bars of 4g same with my wife's iPhone. I once in a great while get a bar of 4g but mostly 3g. Also have you guys been flashing back to the stock 4.3 and 4.4 files before calling Verizon and/or turning your phones in and do you think it's best to go into a corporate store or just do it over the phone? Thanks!
