don't feel bad, bubbles or not, basically depends on the quality and design of these films not your skills!.....I use/used, have/had different brands of screen protectors for my phones/MP3 player and my wife's. Like the one I have on both mine and my wife's Droid X, I have no problem to apply them on the phones, easy and no bubbles!....but some 3-pack trimmable films that I bought from Walmart are the opposite....
