Yesterday I was walking the puppy at a large athletic site. While I was there, my cell phone fell out of my pocket and I did not realize it was missing until I arrive home.
I went back to the field twice, using another phone to call my cell phone but to no avail.
Then I remembered that I had Mobile Me. I googled, mobile me find my iphone and got the Mobile Me website. All I had to do was enter my id and password and the gps in the phone was identified and displayed on a map. I went to a different view and saw it lying in the grass on the soccer field. Hubby retrieved the phone while I made dinner and we are living happily ever after.
This is not an advertisement for Mobile Me but maybe it will help you find a lost phone some day.
AND I am not putting my phone in my pocket again, I'll carry my big old purse with a cell phone pocket inside.
