Currently I'm using the PowerSupport AF Screen Protector..
Very satisfying.. The SP is not the adhesive glue type but static type. I can say, it's perfect.
I applied on my iphone, it suck my itself to the screen without bubbles.
And another good thing is, my friend have it on his itouch, he wants to peel it off and apply the extra AF SP given by PowerSupport.
He peel it off from his ipod then suddenly try to stick back and it works =S
But not sure for iphone. Do it at your own risk.

Just to share my opinion, first casing was the SwitchEasy Color (rubber condom type). Don't like it at all because it's not fit so dust get it easily. Then need to clean often and when u keep taking it out, the rubber already lose..

Second casing (currently using) is the SwitchEasy Capsule Neo, love it, comes with a thin light rubber to protect the back case and another casing. Not as bulky as the Serpent if i'm not mistaken cause my friend is using the serpent..
