Same thing with my iphone4. Thats so weired)
Not a single person I know has the iPhone death grip issue among the 20 or so people I know that have launch day models.
If people have the issue, the solution has been presented: put a case on the phone, or return it if you don't like.
Either way, stop bitching. It's annoying to listen to grown adults whine about not being able to use a phone without an "ugly case!!!!111!!!!"
Go get a droid if you don't like the iPhone. No one is forcing you to be here.
