When you need to exchange contact information with someone, you can do it easily with your BlackBerry. Your address book contains a number of vCards, which are fairly common files containing contact information. We discussed sending BlackBerry contact information with vCards a while ago. The only drawback is that you can’t export your entire contacts list at once. A new app in the Store brings that functionality to your BlackBerry. It’s called Contact Import/Export, putting it in the pantheon of apps that do exactly what the name suggests. There is a do-it-yourself element to this, in that you can back up your entire BlackBerry address book using Desktop Manager. In fact, I suggest you do that often, lest something happens to your BlackBerry and you lose it all. That’s great for your own backup, but there are certainly reasons that having your contact list in vCard format can work to your benefit. For example, one of the AppVerse reviewers mentioned that he can export his address book and then import it into his Android device. Likewise, you can import it into other address book programs, such as Outlook. The app gives you the option to export your contacts as a CSV file, which can be useful for many reasons (I do like having my contacts in a spreadsheet). It also works wirelessly, so you don’t have to plug into Desktop Manager to create the backup/export. And, of course, you can import vCard or CSV files with this app, so you can add a bunch of contacts at once, or you can import an old contact list. There are some limitations — it won’t backup a specific contact’s ringtone, for example — but all in all this is a useful app. You can get Contact Import/Export for $2.99 from the Store, though I recommend, as always, downloading the free trial.
