LG CU400 / CU405

Ok, on the LG CU500 you could not use a downloaded ringtone (from cingular.com for instance) and set it as a group or individual ringer ID, you could only use the ringtones that were default on the phone. I was wondering if the was the case with the LG CU400??? I have contacted LG directly and they are unable to give me an answer...shocker. Can any of you that have the phone give me an answer. I want to buy the phone...but having custom ringtones in a must for me
