First of all let me say I don't work for Pdair, don't know who they are and dont really care. All I know is their screen protector is the only good one I've tried.
Before I got this, I used two dodgy ones off ebay that were so thick it impaired the touch screen, an "Invisible Shield" which cost 40 australian dollars and was basically a tacky sheet of rubber. All of these had air bubbles and made the screen hard to use, not to mention impaired the resolution so everything would get a rainbow glow (Im sure you know what I'm talking about if you've used a bad screen protector).
I got the PDair ultra clear in the mail today and applying it was by far the easiest of the ones I've tried - it went on perfect first go with no air bubbles. Better yet, it completely covered the small scratches I've managed to accumlate on the screen.
When I powered the phone up I found that my finger actually glided over the screen better than on the native screen, the resolution was (as the product name suggests) ultra clear and you really couldn't tell I had it on.
I'm just posting this so people don't waste as much money as I did trying to find something that actually works.
If you're looking for a screen protector for the Touch2 (no idea about other phones), go to PDair and get the ultra clear
