Thanks for this guide - nice to see you are using my device the DHD in the example too
One point though in the past I have had good success using a soapy water technique that lets you reposition the protector till you feel its perfect - then you squeegy out the surplus water and when it dries it stays perfectly in position.
I say in the past because i used the above technique with my current DHD protector and its a flawed technique as there is a small gap around the edge of the DHD and soapy water entered the device and got between the screen and the display. I actually thought the device was ruined but over the course of the next 2 weeks it gradually dried and left no trace of the disaster. However I wouldnt do it that way again.
