Hello - first some clarification is needed: 1) Assume that you have also forgotten your passcode - correct; 2) Do you have a charging cable for your iPad 2 (the old 30-pin to USB cable) - if so that is used to connect to a computer to use iTunes; 3) As long as the iPad is connected to a Wi-Fi network and you have activated 'Find My iPad' in the device's Settings, then the feature works fine w/ a 'locked' iPad; and 4) What iOS is installed on your iPad (8.3 is the most recent)? Dave
P.S. just to reiterate - you needed to activate the find feature on your iPad and sign into an iCloud account.
