I've gotten 3 different answers from the completely lame customer service reps at Verizon. I currently have 4 phones. Two iphone 4S phones and 2 dumb phones. I have unlimited data package. My upgrades are on my 2 iPhone 4Ss only. Can't I switch my upgrades to my dumb phones? Buy the iPhone 5 for both lines and activate them with my grandfathered unlimited plan? Then, switch both iPhone 5 numbers (which were the dumb phone numbers) to my 4S numbers? Then swap out the iPhone 4S phones back to the dumb phones? So ultimately, I'll have 2 iPhone 5s and still two dumb phones and still have my unlimited plan? Has anyone done this yet? Any help or advice would truly be appreciated.
