Windows Mobile 5.0
The biggest difference between Windows Mobile 5.0 and previous editions is that user data in WM5 is no longer stored in volatile memory. This means that the user data saved on the mobile phone will not be erased if the battery is disconnected or has depleted. In windows Mobile 2003, if the battery depletes, or is disconnected for more than 15 minutes, all user data is lost.
Windows Mobile 6.0
Windows Mobile 6 is expected to be released in April 2007. Some users will be able to update their current Windows Mobile 5 to the new 6.0 version for free. WM6 will integrate tightly with Windows Vista. Challenges facing forensic investigators are the support for VoIP and advanced multimedia.
