You are currently using an older version of Blackberry’s operating system. It is best practice to maintain the latest version to get the latest fixes, security patches and functionality.
As we migrate to Gmail, Blackberry operating system versions older than version 6 will require your Blackberry be fully wiped clean (removing all data) during the move. Should you not upgrade before migrating to Gmail, you run the risk of losing personal data including files, images, music, applications or local phone contacts (e.g., business contacts that are only on the BlackBerry and have not been synchronized with Lotus Notes).
Your Blackberry model does support v6 but requires a software upgrade. Your service provider can provide instructions and assist in upgrading the operating system. A backup of your Blackberry should always be first taken using BlackBerry Desktop Manager software available through your mobile provider.
What options do I have?
