Using the http://www.blackberryforums.com/search.php function, I found these instructions:

How to SIM Unlock the device:
1. Go to the "Tools" screen
2. Select "Settings"
2. Select the "SIM Card" option
3. Type MEPPD
4. It should then display a list "SIM, Network, Network Subset, etc..."
5. To select "Network" type MEPP Alt-2
6. It should then ask for the code
7. Enter the unlock code

i got to step 4 . no luck with MEPP Alt-2

Bummer. I found another thread in another forum with identical instructions.

Warning! The Wireless Mode MUST BE OFF before performing the given SIM Unlock instructions in order to avoid causing the device from becoming defective.

How to turn Wireless Mode Off:
1. Scroll to the Airplane Icon (Turn Wireless Off.)
2. Press Select.
3. Wireless Mode will turn off.
4. REMOVE the SIM card
5. Power On the Device (Put the Battery back in)

Make sure you are pressing ALT-2 properly.

I Gave You The Instructions For A 7100.

also when i do ALT MPED in the SIM card option under tools

SIM - Diabled
Network - Active
Network Subset - Diabled
Service Provider - Disabled
Corporate - Disabled

It's called General BlackBerry Discussion.

Network Active means it is locked.

Search for the unlock instructions on the forum please.
