Tip: If you are either selling or donating your old Black Berry, you’ll want to do a factory reset to remove all of your personal data (It’s recommended that you review apps on your computer to be sure all of your data safely transferred).
Now it’s time to sync your contacts from your Black Berry to your new i Phone.
Using the same method used to transfer contacts from Android to i Phone, we’re going to utilize a Microsoft Exchange account within Gmail.
Again, no need to get hung up this being an email account, since we’ve created it solely for the process of getting contacts moved over to your new i Phone.
If you use Gmail, the built-in contact manager is extremely useful because it's used by other Google apps like Google Docs and is accessible from any computer through your Gmail account.
