I've had my 4s for a couple months now and in that time I've bought and replaced about a dozen screen protectors. The reason for this is that I've either misaligned or had some kind of debris on all the protectors before. Now I have an SGP Ultra Crystal and I must say I love it I got it aligned perfectly however, being OCD I noticed there is a little speck of something and I can feel the itch again. So my question is, Does anyone have a somewhat proof method for getting a screen protector on an iPhone without getting some kind of particle stuck before application? Mind you I do the tape on the finger thing already so is there something I can do that will avoid me having to bust out the tape?
