I was not going to upgrade to the iPhone 5s, but my iPhone 5 screen is broke. Is it worth repairing or just upgrade to the new iPhone? It is weird that it was fine this morning before putting it in my left pocket with nothing else. I take it out a few hours later and find the screen cracked from corner to corner. I had an iPhone 4 for two years and sold it with never ever cracking the back or front. I have dropped my iPhone before and have never seen damage on it.
