My current phone (not an iphone) is very close to breaking down and once it does I will definitely get an iphone. I had the iphone 3, when it first came out and it was the best phone I have ever had. Unfortunately it got damaged and wasnt repairable.
I thought i'd try an android phone when my iphone got damaged, but it just doesnt compare. Im not so much referring to the phone itself, but the apps. In my experience, the iphone apps far outweigh the android ones and for that reason alone I will switch back to an iphone.
Perhaps its not the same for everyone, but in my case, all the apps I want and need are only available on apple, plus I love the fact that my phone syncs easily with my mac via cloud.
