Whenever I get a new portable device, one of the first things I do is buy a screen protector, then I have my husband apply it. When hubby got a Blackberry, I ordered these right away. When they arrived, I told him to put one on. Whenever I try to put something on like that, I end up with a mess. Well, hubby waited too long for my taste, so when he forgot his phone one day, I opened these up and stuck it on his BB myself.
