Dropped iphone 4. Blue Screen. What can I do?

This morning i dropped my phone and the screen immediately turned blue. I tried resetting it but it turns white and then goes back to being blue. I can still receive calls but I can't see nothing on the screen and i can also answer it and it sounds fine the problem is just the screen. I don't have warrant on it. How much will it cost to get it repaired? I'm planning to take it to MacResource since they replaced my screen for only $60 which seemed really cheap to me but I don't know how much it would cost to repair it. Please give advice and if you've had this experience please let me know how much it cost to get it repaired or anything that can help me.

Games on my iphone won't work?

I have the iphone 4 and i downloaded the game Subway Surfers. Whenever i click on the app, it opens and shows the opening picture for about five seconds and then the app exits itself. It doesn't even get to the main menu of the game or anything before exiting. I've tried deleting and re adding the app, that still doesn't work. I have also tried re starting my phone. Any suggestions? It also seems to be doing it with the app Song Pop too, but all my other apps work fine? So confused.

How much more would you pay to have a shirt made in the US by Americans?

If iPhones were made in the US by union labor, the cost would only be $20 more per phone. That cost has to be much less for a shirt - if it's the same percentage than a shirt made in the US by union workers would be less than a dollar more than you pay now.

Union workers are paid a living wage, and get health insurance, so unlike Walmart employees, taxpayers aren't paying their Medicaid, and they aren't getting food stamps.

When is it time to finally wake up and see what buying cheap junk is doing not only to those poor workers who died in Bangladesh, but to YOUR tax dollars when you have to pay for what retailers won't pay themselves!
