I'm not sure this is so much as issue with the iPhone screen as it is with the skills of the installers. Most of us regular folks are just not the best at installing screen protectors. I get it right about 50% of the time, otherwise it's a little off, BUT usually acceptable, once and a while I'm so bad I have to rip it off and apply another! Sometimes you can get them "professionally" installed from the vendors. They have experience, and install many a day. It's a good option IF your vendor offers it. Most carrier purchased screen protectors can be "professionally" installed.
