Device Family Reference Designs (DFRDs) are variations of Symbian OS tailored for different types of mobile information devices including one for smart phones, one for pen-based communicators, and another for keyboard-based communicators. There are three DFRDs: Crystal, Pearl, and Quartz

RIM's push technology adds a new and different look at the forensics investigation of a PDA. Unlike traditional PDA's that need to be synchronized with a host computer with the use of a cradle or docking station, Blackberry's are synchronized wirelessly by the pushing of data onto the device. This means that the data on the device could potentially be changing at any moment. Also, a blackberry is never really off. What seems like “off” to the user is really only the display, keyboard, and radio being disabled. So when the device is powered back on to the user, items that have been waiting to be pushed to the device from the server begin immediately. This does not give the forensics examiner the time needed to shut down the device. For this reason, the first step in the acquisition of a Blackberry is to leave it off. The device should only be turned back on when it is in a place that cannot receive a signal and thus nothing can be pushed to it.

Forensics

RIM's push technology adds a new and different look at the forensics investigation of a PDA. Unlike traditional PDA's that need to be synchronized with a host computer with the use of a cradle or docking station, Blackberry's are synchronized wirelessly by the pushing of data onto the device. This means that the data on the device could potentially be changing at any moment. Also, a blackberry is never really off. What seems like “off” to the user is really only the display, keyboard, and radio being disabled. So when the device is powered back on to the user, items that have been waiting to be pushed to the device from the server begin immediately. This does not give the forensics examiner the time needed to shut down the device. For this reason, the first step in the acquisition of a Blackberry is to leave it off. The device should only be turned back on when it is in a place that cannot receive a signal and thus nothing can be pushed to it.
