You know the backstory by now: Sprint boasted that the EVO 4G was its fastest selling phone ever a couple of days after hitting the American market, before abruptly correcting itself and admitting that the EVO's sales were in fact in line with those achieved by the Pre last summer. What you, and we, didn't know till now, however, is that Sprint's self-correction was sparked off by an employee with a curious mind and posting privileges over on the xda-developers forum. On June 6, according to MobileCrunch, this unnamed hero of truthiness browsed Sprint's internal inventory system and nailed down a figure of 65,500 sold units from Sprint's own stores -- a stat far south from what Sprint would announce a day later. That number ultimately found its way onto the message board, and though it obviously shouldn't be taken as authoritative (or exhaustive), it was enough to get Sprint to hit the auto-correct button and part ways with the activist member of staff. Harsh.
