If you backed up your Blackberry device's data with Blackberry Desktop Software, you can only restore that data onto another Blackberry. The other person who posted is correct, Backup Assistant would be one of the ways you could get your contacts, provided you ever used BA with your Blackberry. Sorry.
Do you have a google account?
I'm not sure if this method would work without it.

I think you misread the OPs original predicament. The solutions you provided do not help him get contacts from a BB backup to an iPhone. Your solution only provides for Google, Windows and Yahoo. Any other ideas?
SoccerRef, I apologize for the miscommunication regarding the answer to your post. I have listed below the steps to backup and restore data on your Blackberry using the DeskTop Manager.
Backup Data (Advanced)
These VZW reps just don't get it. First they describe how to back & restore an iPad. Then they describe how to back and restore a BlackBerry. The OP wants to know how to get the contact info from a BB backup file (.ipd) to an iPhone. Be advised that the BB is dead, so using Back Up Assistant is not an option.
The question is:
What are the steps to get contact info from a BB backup file to an iPhone.
This may be a 3 step process. There are a few free/trial programs that will convert your .ipd file to a .csv file (ABC Amber BlackBerry Converter looks like it might be a good one). Then you need to figure out how to convert the .csv file into some thing that will load into you iPhone contacts. This may be your only recourse as there doesn't seem to be a easy solution. Good luck!
