Bubble-free since mid-November until today!

Of the three films have delivered up today the first in use.
My I-Phone, I received November 2011 and had until then only experience with simple mobile phones and their mini-display.
Simple written:
I could attach the protective layer completely over the entire area and it sticks still problems. Therefore, an unconditional recommendation on my part.

At the edge of my approach to the attachment:
First, I had to have the room lights turned up to a maximum of the best view of any dirt particles.
The display surface of the 3Gs I had cleaned with a clean microfibre cloth and a tiny amount of washing up liquid, while the fabric still moistened only at one end). The surface was completely free of grease and free of particles.
Then wait a moment, had reduced to dust swirled in the air and then removed (which was also important so that the plastic layer of the protective support can catch anything).
Multiple the display breathed and wiped dry with the end of the cloth.
Then I took the first seal.
Then followed the sacred moment of rest for guidance. And I oriented myself to the two openings / recesses in the protective layer.
Then I squeezed out the air bubbles from the center direction side. With a credit card, I also tried it, but better results I achieved with their own fingers.

The Result:
Most falls not on that I've ever mounted a protective layer on the display. When I jumped into my eye a bubble landscape in the view of another I-Phones, I understood why. ;-)
This part of my 3G and I managed to achieve an optimal result.
