So I was planning on trying out the iPhone to see how I like it and it seems like good time to do that with the 5S likely launching pretty soon. I figure its going to be more of less of the same phone with a faster cpu/bettercamera/fingerprint/flash so I'll get a good flavor for things. My goal was to try out the phone and test it out for 3 weeks or so until the new one launches. Then return this one if I want the 5S or just keep it if the differences are super minor. Thoughts?
