My wife and I are currently have Verizon iPhone's, a 4S and 4 with unlimited data plans. My wife and I are due for upgrades this December. My question is, am I grandfathered in with unlimited LTE data if I buy the iPhone 5 with a new contract? If not, if my wife buys the new iPhone 5 and signs a new contract with a tiered data plan, can she transfer the iPhone 5 to me and will I be able to keep the unlimited data with LTE since I wouldn't technically be signing a new contract (I use much more data than she does)? And I give her my iPhone 4s. Sorry if it seems confusing. Thanks!
