You get the option of performing a factory reset (wipe device internal storage) or wiping the removable storage area (SD card or SIM card).


However, if you choose the Factory Data Reset you cannot use the Find My Mobile service any more.  Once you have chosen the type of wipe, you have to click on the View full Terms and Conditions feature and agreeing to it before you can perform the wipe and you cannot just agree with the terms and conditions without clicking on the View full Terms and Conditions option that appears.
