There are ways to backup the address book on BlackBerry. But saving it to the memory card is not one of them. Saving your contact to the SIM card is possible but not practical. Due to the limited memory available on the SIM card it only allows the saving of name and one phone number. Therefore, you cannot store information such as a contact's address, more than one phone number (e.g. home and mobile), etc onto a SIM card.
They are three ways to backup the address book:
1. If you have a Gmail account you can download Google Sync free from http://m.google.com using your BlackBerry phone. This application can sync your BlackBerry contacts and calendar with that of your Gmail account. This is probably the most convenient way of backing up the address book.
2. If you use Microsoft Outlook, BlackBerry Desktop Manager can sync the BlackBerry address book with your Outlook contacts.
3. In BlackBerry Desktop Manager, goto Backup and Restore/Advanced, select Address Book from the list and save it into an .ipd file. If you would like to restore the Address Book simply go to Backup and Restore/Advanced, locate the .ipd file on your computer's hard drive and reverse the previous operation.
This seems really silly but I have created my address book and now cant find how to save it on either the sim card or media card.
Created it once before and then phone broke and the replacement didn't have all my info on. Think it should be going on the sim card. Can anyone help PLEASE ?
