So here is the 10,000th thread regarding keeping VZW unlimited data. I am looking to swap my iphone 4s with an iphone 5. Here is how my plan is structured. My phone- Iphone4s with unlimited data Sisters phone- Dumb phone I was thinking that I will use my sisters upgrade to buy the Iphone5 and get 2gb of data on that line. I will then swap my Iphone4s with the Iphone5 keeping my unlimited data on my line and my sisters Iphone4s will have the 2gb of data. Am I missing anything here ? thanks!
