I've always just kept my 4s because I have unlimited 3g data and I always enjoyed being able to just listen to Spotify and Podcasts freely without worrying about data. I don't use my phone for much more than that as of now. How I understand it that will be going away starting tomorrow. I'm eligible to upgrade anytime, so should I update now and sign a new 2 year contract for the 6 or wait and do the new structure and get the 6s? It will be part of a business plan which has around 10 phones on it. Thanks!
