I ordered a X220 on 05/13 and the ship date estimate is 06/07.
However I just received shipping confirmation email today.
Status: Shipped on 05/17/2011
PS: I called to request a change from wireless N1000 to N6205 over the
weekend and was told that a request was sent to warehouse to remove the
original order. But it seems like that it doesn't work at all.
