Slick iPhone Tips and Tricks

I thought I would throw this out there and see if anyone has come up with something OTHER THAN A SKIN for the iPhone's slippery-ness.

I don't know of any product other than a skin to help the phone not be so slippery. I LOVE the way the phone looks. And the skin I bought for it is okay too. But I would love it even more if there was some way of just adding a strip of texture to the sides...you know...for grip.

Anyone have any suggestions? I'll post back if I find something.

Thanks
Jenny
