ABC Amber lets you edit your Blackberry Phone book from your blackberry backup file. Pretty cool and now its free! Berry Review made a good post with a screen cap.
“ABC Amber BlackBerry Editor is an easy-to-use, award-winning program that helps you manage contact information in IPD (BlackBerry Backup) files.
You can retrieve an address book from IPD file, edit it (full name, company name, job title, phone numbers, home and work addresses, etc.) and then put it back on BB.
As all ABC Amber products, it’s really easy as ABC and powerful as Amber. ”
