I sorta did the same in the interests of dual-boxing.
I did a dumb, though. I attached the Android authenticator to it, paid for a month (and the game itself, of course, so I at least got the free month on my main account) then reflashed my phone without even thinking about it. Maybe if I get unlazy I'll just call up billing and get the authenticator removed (it's only a secondary account anyway, though I do get the Core Hound Pup...).
Even the relatively-dumb dual-boxing that I'm doing makes leveling a whole lot easier, aside from those dumb gather quests.
