I read on a forum many years ago about making your own screen protectors from this clear vinyl sheeting stuff in the walmart fabric dept. (it's the same stuff that protects the display on a new bluray player or clock radio that you peel off, I got enough to make hundreds of protectors for like $2.)
I used water to put those on and never waited. I was maybe a little more careful putting the phone into my pocket the first day after installing so I didn't peel it up, but I never had any problems.
edit: oh hallo old thread.
