Dropped my iPhone recently in a cab and found out how difficult it is to search for information on the go. It was the 2nd last day of 2011, and we were in a premier taxi when we decided to alight at cineleisure in a hurry because the traffic was so jammed. Paid, and got out of cab, only to realize I dropped the phone on the taxi's floor (because my sister checked the seat when she got out). I patted my shorts, checked my bag for the phone, and meanwhile the taxi got further and further away. Called premier taxi, and my phone which rang (but it was at vol 1) and tried chasing the cab down (too late). Premier taxi service said they would page their drivers after getting all the necessary details – but I have no cab number, nor do they have gps tracking on their taxis so even if I know where my phone was at they can't contact the driver. It was then that I realized I've the "Find my iPhone" service in my phone so after a good 15 minutes of initial flustering figuring out how to access that service – I need to go to www.icloud.com or install the Find my iPhone app on another iPhone, enter your apple ID and password, I realized that the phone was tracked to Dorset Road.. and I quickly managed to remote lock the phone with a passcode. After that I decided to send a message that will play along a sound at full volume – on hindsight perhaps that's what alerted the passenger to the phone and to steal it. The message included my sister's phone number asking for the person to contact the owner of the phone, and it got sent as well.
