As the titles says, my iPhone 4 (black) dropped from my car while driving, the front glass is destroyed, some parts of the glass (around the proximity sensor and the front camera are gone, around the home button too). I think the proximity sensor isn't working properly, sometimes it works, other's don't. I can't take it to an Apple Retail Store, because there's none in my country. How can I repair my iPhone 4? The premium reseller repair cost too much. Where can I buy the front panel and repair myself?
