I have an iPhone 5. Upgrade available in March, but I've been told I can upgrade early. I want a larger phone like the 6s. Is the next phone going to be the rumored 5se, or possibly the 7? I don't want to wait until March and it is the 5se, and just end up getting the 6s, when I could get it now. Any idea what the next phone will be, and when it's coming out?
