I just had ATT provide me my unlock code for my UK trip. Can someone tell me the process of where/when to enter this?

Do I need to leave my ATT sim card in or out during the process?

Will I get a confirmation on the screen that it got unlocked?

At the airport now so thanks in advance....

Right from the handy dandy FAQ page....

How do I unlock my BlackBerry? - BlackBerryFAQ

i just unlocked mines as well. but follow the link above, and just so you know i did not get a confirmation it was unlocked, but when i put in the new sim card it worked, and then i had to select my carrier and oh yeah i left the att sim card in as i unlocked it.

You won't receive a confirmation message that the phone is unlocked. Follow the procedures in the link and it will be unlocked.

Excellent guys - landed in London and just checked the response. Sorry, for the original post but I was at the gate for boarding and it was just easier at that time to post as opposed to search via my BB.
