basically download Google Sync to your iPhone, then sync your contacts to Google Sync. Install the same on your blackberry then sync contacts again to your blackberry
Thank you for the second option.....a very good, clear step by step explanation/description although I am still having problems.
if you follow it correctly, it should work.weird that it doesnt workout for you
try to download a app called bump on both devices ( blackberry and ipad)this app let your transfer contact by bump to two devices.
sorry I forgot, bump app is different on both ipad and blackberry
sorry there no more option to transfer contact than google sync and desktop manager for blackberry sync to outlook and itunes sync with outlook
