This work-around is limited to iPhones with firmware versions 1.1.2 and earlier. The work- around was disabled on version 1.1.3 in February 2008.

Data can be retrieved from the SIM card as well as from the phone handset. To remove the SIM card, place a paperclip in the hole at the top of the phone. Force must be applied to get the SIM holder to pop-up.

The SIM card will be inside a plastic tray and can be easily removed. Process the SIM card as normal. To access the locked handset, follow these instructions: From the keypad, press the cEmergency Call d button.

If you are able to guess the Passcode, or find it from a brute force attack, the contents of the phone can be copied using a fresh installation of iTunes. Special thanks go to Mr.<br><br> Curtis Thomas of the FBI 9s Forensic Electronic Device Analysis section for walking me through these steps. The screen shots came from an actual case and the pertinent information was redacted through the use of blackout boxes. <br><br>
