Planning on buying Unlocked Sidekick LX. Does it work with AT&T/Cingular sim cards? ?

I currently have AT&T/Cingular but I want to buy a Sidekick LX. I can't switch services because my two years aren't finished yet. Does anyone know for sure that unlocked sidekicks work for AT&T/Cingular?

yes, i know for sure an unlocked side kick will work on an AT&T simcard, you will only be able to use texting and your phone, no internet, no AIM, and im pretty sure no games

I just bought a unlocked sidekick lx 09 and have my att sim card coming. I have heard from att employees that I will be able to use all the features on my sidekick with att. Even data. now with att in the works of buying tmobile wont i be able to truly use everything they say I can?

also, I have read of people who have unlocked the data for att and it worked. has anyone tried this and it worked?
