iPhone 3GS lost and can’t use Find my iPhone My iPhone 3GS was lost and I don't have any iOS device to login and erase the data. 

I logged in using the browser on my Windows PC but it says I need an iOS device to locate my phone. Can I erase the data I have in the phone in any other way?
You can use any browser to go to https://www.icloud.com/#find &amp; track the phone, play sound, erase it or lock it - so long as you know your AppleID &amp; password.

If not, start at iforgot.apple.com
