getOrgUniqueName() returning a GUID value?

Hi, im currently using CRM 2011 online. and I am using this line of code in my javascript:

context.getOrgUniqueName();

 I am getting the GUID value of the OrgName instead of getting the "friendly name" of my organization. I am wondering why does it behave like this, I have tested this in 3 different browsers already. Thanks.
