I have been going back and forth with the iPhone 7 since launch day and finally decided to go back to the 7 and stick with it. As luck would have it, the 7 that I bought yesterday was an RF dud. Sitting next to my wife's 6 with three bars, this phone was showing "No Service" or zero bars. I spent 4 1/2 hours with Verizon trying to troubleshoot the thing, going up through several techs. We went through many resets and restores and changes of SIM card and just about everything else you could imagine. I went back to the Apple Store today and sonuvbeech as soon as I get into the mall it starts showing 4-5 bars. I explained the situation to the Genius who did a little investigating and disappeared into the back, coming out with a new (and that's new, not refurb) iPhone 7 jet black 128gb. He handed me the phone and gave me the charger, cords, etc. from the first phone for my trouble, and then installed a new glass screen saver to replace the one that I'd installed on the phone last night. I know we hear horrible stories about experiences at the Genius Bar, but these guys really treated me as good as you could possibly expect, maybe better.
