I've learned how to fix many iDevices...I'm a youth pastor and SO MANY students have broken screens! I started fixing their stuff at my cost to help them out...now that I've learned a lot, I'm venturing out to help others at a good price.
I broke one power button, bit that was one out of seven devices I've fixed now. Know what I did and wont do it again!
GO SLOW & have patience. If you get frustrated, walk away & come back. Fast hands and frustration lead to breaking other parts of the device!
