Wait wait wait, I think you guys are getting confused. Just because a piece of software came preconfigured does NOT mean that BFL was mining on the hardware before shipping it. That's the worst case of deductive reasoning I've seen all week.
EasyMiner came preconfigured with a default pool/worker, and we're all assuming that this is a BFL account where BFL gets the earnings from. This make sense, as they prolly have to ship their software with some default settings. Personally, CGMiner did it better by shipping with no default pool/worker info, so you HAVE to enter in your info. But that's besides the point.
Ok, yes!
OP: did the miner log in to a pool account and start mining for it, and do you have the account details?
-or-
did it just have default values for some testing pool and that's that?
ps: i dont really know anything about this, im just seeking clarification.
