That's silly, of course. The iPhone is a tool and should be treated as such. To ease my mind, I ordered an Invisible Shield. We've discussed Invisible Shield a number of times. Basically, it's a super-strong film that you apply directly to your precious, keeping it from harm. I saw a demo at MacWorld a few years ago, and was very impressed.
Once it arrives, I'll let you know how it performs. Invisible Shield for iPhone comes with a lifetime guarantee, costs $24.95US and is shipping now.
