9930 Screen Protector Tip
So, the 9930 comes with a little plastic screen protector, but it has a flap hanging off the top which makes it unusable for the long term. The trick is to cut the little flap off with scissors and you will have a perfectly fitting no bubble screen protector on the phone for free.
Obviously if you already pulled it off it is too late, but keep this in mind for future phones. I've been doing this with devices for the past 2 years and it's the best way to protect your screen.
