I've been using a metal flat opening tool along with the suction cup to pop these bad boys open - remember the tape on the screen trick if you have a smashed screen - so the suction cup can grip and stops the glass going everywhere!

so easy compared to the iPhone 4 - took me no more than 30 mins on my second phone - can be tricky if the frames been bent from a drop as my first one was. Good stuff - keep up the good work
