My I-Phone 6 is lost... I know the usual drill but

If you had "Find My iPhone" enabled in Settings > iCloud then you may be able to locate it. If not, you cannot locate it.

If it was enabled then you can try locating it via http://icloud.com on a computer or the App "Find My iPhone" on another iDevice. You can also tell your iPhone to "Play Sound", enter "Lost Mode", or "Erase".

Note: this will only work if your device is connected to a network and the device hasn't already been restored as new and/or "Find My iPhone" has not been disabled on it. Note: Disabling "Find My iPhone" is much more difficult in iOS 7/8.

If you think that your device was stolen rather than lost then you should report it to the police. In either case you should contact your carrier, change your iTunes account password, your email account passwords, and any passwords that you'd stored on websites/emails/notes etc.

The Find My iPhone App is irrelevant. If you turned on Find My iPhone in Settings->iCloud on the iPhone is what's important.

As that engages Activation Lock:

With Activation Lock, your Apple ID and password are required before anyone can:

• Turn off Find My iPhone on your device
• Sign out of iCloud on your device
• Erase and reactivate your device

iCloud: Activation Lock

If it has not been restored, it will need to connect to the internet either through cellular or Wifi, to send its location. Its last location is displayed for up to 24 hours. after that, the last location is no longer displayed.

iCloud: Locate your device

Just a vent....I know it is my responsibility to keep up with my phone but for $950 you would think Apple would have some kind of way to find the thing and keep others from erasing it and turning it on. In the future I am thinking of just getting a cheap *** Metro for $49 a month. You get the same results if you lose it so why bother...

No one can erase it without your Apple ID and password. If you had set a screen lock passcode no one can use it. And you can find it when it is turned on. If the thief never turns it on it is no use to them. It's no use anyway, of course, with Activation Lock enabled. Just watch out for phishing scams. If you get a text or an email claiming to be from Apple, with a link to enter your Apple ID and password, don't do it. Even if it looks exactly like an Apple page.

The serial number will be on the Box the iPhone came in.

Other than that, you can go to https://supportprofile.apple.com/, and if you added your iPhone to your profile the serial number will appear there.

I did not write down the serial number from the phone. Will it be in my paperwork or how would I find it?
