Cingular Tmobile

How do you unlock a tmobile sidekick and put a cingular sim card in it too work?
well I want to get a sidekick phone but I have cingular and im on a 1 year contract so I cant really change my services right now . But I read online that if you unlock a sidekick you can use it with any services is this true and if so can someone help??
Good luck with that. Sidekicks are VERY hard to unlock. T-Mobile can’t even get an unlock code for Sidekicks. Even if you were to manage to unlock a Sidekick, you wouldn’t be able to use any of the data features when using it with a provider other than T-Mobile. Sidekicks require special data servers from Danger, Inc., which can only be accessed through T-Mobile’s network.
