Lost the mobile!

This is the 3rd mobile I am loosing in the last 8 years! My bad! We had been to a park nearby along with friends and I have no clue of when it slipped from my hand.

The mobile is less expensive one but two factors worry me a lot :(

• One being too careless
• And the other is for not taking backup of my contacts.

Hope to be careful with my things atleast from now on...
