bestskinsever...peeling? Am I doing something wrong?

[ibTom]

I've bought several bestskinsever skins for my iPhone and they always seem to start peeling after a month. I keep the phone in my pocket, and after a while I can see some buildup on the corners. Eventually it leads to peeling.

Anybody else experience this? I allow the skin to cure overnight for about 8 hours. I can't leave my phone alone for 24-48 hours, just not feasible/practicial.
