So I just got fired from my job, and when they wiped my BB off their BES it took all my numbers with it. I back up my numbers quite often, so I have an Excel file with all of my contacts. I don't have Office at Home, so how do I get them onto my BB besides going one by one and entering them?

1- Import Excel file into Outlook, and sync to the BB. <- easiest.
or
2- Save Excel file as CSV file, and sync to the BB

Sorry to hear of the job loss.

Being that I'm also pretty dumb, how would I sync from the CSV to the BB?

After installing Desktop Manager installed to your PC. Configure the sync setup...

1. Connect your BlackBerry® device to your computer.

2. Open the BlackBerry Desktop Manager.

3. Click Synchronize.

4. On the Configuration tab, click Configure synch.

5. Select the Address Book and in the popup window, select CSV file.
