Did your iPhone stop working or is it malfunctioning? Did your iPhone suffer water damage? If you are not sure what is wrong with your iPhone or what needs to be fixed we can perform a diagnostic on it to see if it can be repaired. We can usually tell you what needs to be repaired or fixed by looking at your iPhone for free, but if we cannot tell without opening it up we can do a diagnostic/evaluation on the iPhone to see what is wrong and give you an estimate of what it will cost to repair the iPhone. The cost of the diagnostic will be applied to most repairs you have done to the iPhone so it usually doesn't cost you anything extra as long as you have the iPhone repaired.
