Your BlackBerry can store plenty of emails. In fact, if you so choose, you can have it store your BIS emails forever. Combined with a search function, this can become a valuable tool. It can also, after time, take up way too much device memory. That leaves plenty of room for an application that dumps your BIS emails onto a memory card. The folks at Virtual Fidelity have filled that need with their BlackBerry application, Virtual Vault. It helps save room on your device by dumping BIS emails onto an SD card, complete with search, edit, forward, and reply options. It sounds like an excellent email archival tool. Virtual Vault saves all of your BIS emails, both sent and received, for easy access later. Within Virtual Vault you can search for emails and then edit them, forward them, or even reply to them. You can save many different vault files, so you can keep things organized. These are encrypted files, so you don;t need to worry about security. BIS users can get Virtual Vault for $9.99. BES users should have a version in the next week or so.
