Hi. Today, I am one of those unfortunate iPhone 4 owners to have one missing and possibly stolen since nobody bothered to return it. I was on my way back from the airport to my apartment. I live in a 25-story apartment building, and am 100% sure it is in possession of someone within this building. The reason is because I had it in my hands when I got out of the car when arriving to our apartment tower, and put it in my jacket pocket so that I could grab my luggage from the trunk of the car. When I got to my front door of my apartment on the 14th floor, I noticed my iPhone was no longer in my pocket. I immediately traced back all my steps and could not find it. It was my mistake for putting it in a jacket pocket that had no zip. I had a duffle bag on top of a carry-on, and it fell off the carry-on while rolling it... and I feel when I leaned down to put it back on the carry-on when inside waiting for an elevator to my floor, it must have slipped out of my pocket. I never had location services turned off before, but this time I did. My battery was really low from the flight and I just wanted to conserve as much possible to make sure I had enough power for an emergency call on the way if necessary (also had turned off 3G, and lowered brightness). I do have MobileMe, but all I could do was send a text message with sound since location services was off. I did this many times throughout the day, and when I call my phone I still hear it ring 3-4 times before it goes my to machine.. so I don't think anyone turned the phone off. I tried to play the MobileMe sound using "find my iPhone" as I retraced my steps but could not find it. It's sad to know that someone in my building has it and I can't do anything about it. I left my info with the Front Desk and the Leasing Office as well. I also left this info via message through MobileMe on my iPhone 4 as well. The phone was on mute/non-vibrate and password protected, but I heard that the sound will still play in this scenario. Now.. I need to get another iPhone 4 in case this one does not turn up. I have heard stories that they want full price if you get another one. I had bought mine as a pre-order from Apple back in June. My parents are on a separate family plan and my mom is eligible for an iPhone 4 upgrade for $199 at 16GB. I am not on their family plan, but was wondering if I can receive her upgrade, order the phone online, and have it shipped to me? She is completely okay with it. It's just that I have my own personal plan and a different number with different area code than her.. so not sure how the whole activation process will work since my already-activated micro-sim is also gone with my lost/possibly stolen iPhone 4. I live in NY, if that means anything.. while my family (and their family plan) is in Cali. Thanks for your help.
