Default Having problems switching carriers... do I need to unlock it?

Please Login to Remove!

I recently switched from Centennial to ATT.... I got the sim card today for ATT and attempted to put it in my BB. It will not read. It reads Invalid Sim Card at the top of my bb, and still starts up reading Centennial. Do I need to unlock it? and if so - how do I do that? I have no clue what to do to make my ATT sim work for my BB, but I will go insane if I have to use this little baby phone that they sent me..... :( PLEASE help me make this work!!! THANK YOU in advance!! Oh - its the 8310. thanks!!
