Can anyone help me!
I had a nokia En71. I copied all my contacts on the small memory card and inserted that into my new Blackberry Bold 9000. What I want to know is how to transfer it from the memory card to the phone.

You can't on a blackberry.
A blackberry can only read contacts from a SIM card.

You should probably look into transferring the contacts via a PC. I wouldn't recommend even using the SIM card approach unless you only have one phone number for each contact and no other data.

Be sure to backup/and or sync regularly once you're on the BB.
