Why does my iPhone forget it has a SIM card when I keep it in my pocket?

Strange phenomenon. My iPhone 3G often forgets that it has a SIM card. That is, a "No SIM card installed" box pops up in the middle of the screen, and I've got no phone/3G service. Every once in a while it's "Invalid SIM," but usually "no SIM." Powering down the phone and turning it on again fixes the problem, though about 1 in 10 times I need to power down and up two or three times.
I have noticed that this ONLY happens when I keep the phone in my pocket (though it doesn't happen every time I keep the phone in my pocket.) I take the phone out, and "No SIM."
Does anyone have any idea what's causing this? Or whether there's an easy fix other than keeping the phone in my bag all the time?
