I concede that there's some stuff on your phone that you don't want spread around. However, I refer you to the ipod touch story - the woman who found it was not tech-savvy. Though she had good intentions and wanted to return it, she didn't know how to use email. Those people are more common than you think. Maybe your parents or spouses phone number?
Even then, you have to hope that the person doesn't have phone phobia (like me) and isn't deaf (like me), to phone. With full access to the phone, most people can find a contact mechanism that works for them.
