How long after a cell phone comes out does the company start selling them as Refurb?

I'm thinking about getting an oldder model of the phone that is also a Refurb from my cell phone companys website, but the newer model has been out since Oct or Nov of 2006. How long after a cell phone comes out do they start selling on ther website as Refurb?

There really isn't a time line on that. Refurb are simplely phones that were broken somehow, repaired and now are being resold.
