Tonight a coffee cafe, I dropped my iPhone 4 from the counter to the ground, which was around six feet. (I was without a case, by the way. Coincidentally, I left the house asking if I should bring it or not.) I picked up, the phone laying screen-first. Nothing was cracked, and I put in my pocket. Afterwards, I was drinking my coffee, and I noticed the screen only showed a blue, fairly dim light. I can still receive calls, texts, and that stuff, but can't see anything. Is this a common problem with iPhone screens breaking? I'm always careful about my devices (which, surprisingly, I'm not terribly upset about being without an iPhone. I've become addicted to it as of lately), and needed some help regarding this issue. Should I send it into Apple for a refurbished iPhone 4, or go through a company that fixes this problem?
