I ordered the pentalobe screwdriver to change the back cover on my Iphone 4 due to weird pictures I had been taking. The back cover and other parts are on another order and I am in a holding pattern for the home button due to time constraints. However the screwdriver helped me to change the back cover and made my pictures "Picture Perfect". Thanks for all the great info and I am telling everyone I know that has a repair to check you all out.
Stay off hard drugs!
