The Sprint EVO 4G had the most successful opening day in Sprint history. Interesting that they mention 22,000 stores and beating the previous record of Instinct and Pre, but curiously never actually say how many were actually sold. Meanwhile, Apple had no such secrets in that regard even when gaffes were involved: 400,000 iPhones sold on the first day of pre-order, causing many of the AT&T eCommerce servers to crash and/or send erroneous emails.
