My client dropped her phone and cracked the screen pretty bad.
The repair process was slow going but I completed it successfully. The next time will be much faster for me though. However, I did order a faulty screen from some moron on Ebay, so I now have to complete the repair again, but no worries. I am very comfortable with the process now, and a word of advice....Do not order any iPhone parts from a company called ZYdistro on Ebay. Their parts are cheap and they will give you a hassle about the return process.
Get a good quality screen from a reputable seller like here at ifixit.com or etechparts.com. I learned the hard way to not take any chances with sellers on Ebay.
