I found this cute little tutorial on making a keychain smartphone tripod:

For instructions on how to make one for yourself visit:  http://www.benvelo.com/phone_tripod_3.htm

I first heard of Benny from http://www.diyphotography.net/cleverest-diyp-iphone-tripod-ever/

But I like the version above better than the version 2 feature in that article.
