Sorry, I didn't mean to say that you didn't have a valid point. It's good to make people aware of these things. I just really like researching things and backing it up with evidence (I can't help it, I have just completed a science degree at uni).
It's just that I think you will have broken the phone, the battery will be flat, or any other combination of things before you have to worry about the screen going on you. Or you bought a new handset with a 2 GHz processor with a full HD 3.2 inch display
