Hmm, what do you make of this post then?The Power Support anti-glare's are the best in the biz. Don't be fooled by cheap imitations on ebay, you'll just be wasting your time.
I use SGP STEINHEIL OLEOPHOBIC, they do the job perfectly for me; as good as anything I had on my 3G. Also can be had for half the price as the "always overpriced and overated." Power Support range.
You lose no picture quality with the SGP; unlike other brands.
Oh and some form of screen saver is essential imo.
