I just reread my receipt for the Droid I bought 31 days ago over the phone. In the Return/Exchange Policy section, it states that the item must be returned/exchanged within 30 days. A little further down, it says "Exception: All items purchased between November 15 and December 14, 2009 may be returned or exchanged through January 13, 2010. All other provisions of [...] Policy continue to apply."
Unless there's a catch, I take that to mean that I have a few more weeks to decide if I like this thing or not.
