I ordered a new iphone 4 screen and after installation it lasted about a day and quit. The girl I installed it for worked for a daycare and couldn't be without it in case they had an emergency. I didn't have a spare screen and she had to go to another shop to have one installed. I have tried to find out what I need to do to get a refund and Zeetron will not get back with me. They have ignored about three emails I have sent them. I was worried about the screen when I pulled the plastic off the back right before installing and it had a big thumbprint and glue splattered on it.
