I currently have the iPhone 4 and have no real complaints. It amazes me that any such device could do what it does, but the idea of owning a 5s is tempting. Through the internet rumor mill it appears people are suggesting holding off on buying the 5s in anticipation for the the 6. Unfortunately, that shouldn't be out for another year. If simply the 5 were available, I would make the purchase without hesitation, but since it is no longer available via service providers my only option would be the 5s. Any suggestions here? I'm real close to pulling the trigger. I would also appreciate the extra space as my iPhone is my primary mobile music player.
