My dde was showing 7-12-08---10-10-08 yesterday, when I took delivery of my smart, in ABQ N M.
So it looks like if you take the day on the first dde & add one month to that date, that maybe when you get delivery, AS I GOT MINE ON 8-12-08.
My reg # 1281---conf 2-15-08--Y/B/B
Hope this helps some of you, who are still waiting for your SMART.
