So I fix iPhones, like a lot. Mostly just the 4 and 4s right now. However I have a feeling I will be asked to fix more and more iPhone 5s once the 5S is released. I have started to research how much it would cost for the screens to figure out how much to charge. I buy the glass, digitizer, and LCD already all together as I have no idea how to perfectly fuze them myself. iPhone 5 screens are $130 on the low end on eBay. iPhone 4/4s screens are only $30 on the low end. Where do these company's but their parts that they can fix an iPhone for $100? Someone has to know! Thanks!
