finding my stolen phone iPhone 4S

Did you turn on Find my iPhone in Settings before it was stolen (this has nothing to do with the app, whose purpose is to find OTHER iPhones)?

Assuming you did, have you logged on the your iCloud account and clicked "Find my iPhone"?

What message did you get?

Find my iPhone will only work if you enabled it in Settings, and only if the thief did not turn the phone off, remove the SIM, restore the phone as New, or wrap it in aluminum foil.

yes lawrence.. app was on and i had tested the app few days back and it did manage to locate the phone.

after it got stolen, app is not able to locate the phone..i guess its switched off or they've changed the SIM..My phone also had login pasword..I managed to send few messages to my phone using the phone but I haven't received delivery receipt..

fortunately, I managed to find my IMEI no for my lost phone..would u know if Apple can help track the phone ?

Like any ohter maker of any other phone, Apple can do nothing.

Sorry.

Report it to police, alert your carrier and change your passwords.

That is all you can do
