The Blackberry is a wireless handheld device that supports e-mail, mobile phone capabilities, text messaging, web browsing, and other wireless information services.
The Blackberry was first introduced in 1999 by a company called Research in Motion (RIM).

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.
A good way to be sure that the Blackberry is not sending and recieving when you don't want it to would be to place it inside a "Wireless Stronghold Bag". Parabin Corporation, one of the leading companys in the development of cell phone forensics, sells such bags. First responders can use this bag to ensure proper wireless lockdown procedures are followed and that the evidence is protected from potential case killers such as after seizure wireless communications.
The special tri-weave material used in the "Wireless StrongHold Bag" is made of a Nickel, Copper, Silver Plated Nylon plain woven fabric. This fabric is key in preventing unwanted signals from tampering with your evidence.
Parabin sells these bags on their website at Paraben Corporation.
