International Mobile Equipment Identity or IMEI number is a unique identifier used for all GSM- WCDMA- and iDEN mobile phones.
If your phone is stolen the only way to block the thief from using it is by blocking the IMEI number.

This is done by contacting your mobile-operator and ask them to block the IMEI number.

Therefore I made this simple application to extract the IMEI number and send it to your email account so you can store it and retrieve it whenever necessary.
