My iPhone 4 is broken and I don't know?

I have an iPhone 4 (not the 4S).It's fairly new, I got it in April of 2013. The other day I dropped it on the bottom of the phone and the entire back of it popped off. At the bottom two hooks snapped off and allowed the back to come off. My phone will not connect to my service provider but connects to Cellular Data. It won't allow me connect to wireless internet either. Anyone have any suggestions. Or tell me how much a repair/replacement will be? Or how long repairs will take before I get it back. The back doesn't want to stay onto the phone either.

There's a small ribbon cable under the glass at the bottom of the iphone for your Wi-Fi, probably broken. I would take it to a reputable repair facility for repair, the replacement lcd on those is 40-60 bucks and the ribbon cable is cheap, if they don't break the glass when they take it off, it should be a 50 dollar fix, best case scenario, 150 worst case.

  • Upset and worried and don't know what to do I got told by my mum when she called me from work saying police are going to track down my iPhone. I don't want that to happen and I'm becoming increasingly worried and upset. What should I do to make sure I'm safe? )
  • People that buy iphones don't know anything about technology did you know that? Like my friend just brought iphone and I asked him if it has 4g late he said what's that? Then I asked how fast is the processor like 1.2 dual people buy them because its more mainstream and because their friends have iPhones Samsung is way better based on specs and technology the iPhone 4s and 4 processors are very slow
  • Not enough iPhone storage and don't know why? I want to update my iPhone 4 8GB to iOS 6. I deleted All my apps. Deleted hundreds of photos, contacts, notes, and emails. Still not enough space. I only have 1.8 GB available but I need 2.4GB. I have 1, 008 photos now and like 95 contacts. Also about 230 emails. No apps. My friend had more photos than me and had no problem. What is using up all my storage!
  • My iphone is broken and I don't know what's wrong with it? First of all the front and back is cracked which I know how but can someone tell me what's wrong with the screen because when I turn it on or go onto an app or something you can see faded black lines in the background which are not suppose to be there. It is an iphone 4s btw. Also it turns off by itself sometimes. Please could someone tell me what's wrong and how much it costs to fix?
