How can I unlock the Sony Ericsson W518a when I already have a unlock code from AT&T?

I now have the unlock code from AT&T, but they did'nt let me unlock it until the next 90 days.

But I think, since I have the unlock code, I can personally unlock it !

Does anyone know how? Please tell me.

Thank you very much and have a good night !
By the way, please also tell me which kind of memory card do I need to insert into the Sony Ericsson, because I inserted the Micro SD Card into it, but it didn't recognize it. So I think Micro SD is not the right memory card for this phone.

Take out the SIM card and go from there.
