So I understand how to keep Unlimited Data through the "Verizon Loophole" 1000+ thread but I haven't ran into any posts that asks if the IP5 is purchased through a vendor, would it still work? I was at Sam's the other day, and tried to use my wife's upgrade to buy the IP5 for $127 and activate it on my line, but the guy says he cannot do a "cross activation." In my understanding, one of the ways to keep Unlimited Data is to use a secondary line upgrade to actually activate the IP5, then later deactivate the IP5 and reactivate the original phone on the secondary line. And reactivate the IP5 on the main line (or whatever line you want it on). I wonder if it would work the way since everything is essentially the same except the phone is bought through Sam's (or any 3rd party vendor) and activated at Sam's?
