Apple's '12 Days of Gifts' continue with free 'Tiny Thief' iOS game [u]

The second day of Apple's newly-expanded "12 Days of Christmas" promotion originally made the pilot episode of popular television drama "Once Upon a Time" a free download for U.S. users, but it has since changed to the iOS game "Tiny Thief" without explanation [updated].

Update: Apple appears to have swapped Friday's gift at midday —  Tiny Thief, a game from Angry Birds publishers Rovio, now appears for U.S.-based users in place of "Once Upon a Time." The reason for the change is unknown, though Tiny Thief was the second day's gift for most locales outside of the U.S., which was gifted the pilot, and the U.K., which received an episode of a BBC nature series.

"Once Upon a Time" is a fantasy drama series in which viewers can "join Emma Swan, Snow White, Prince Charming, Rumplestiltskin, Hook and the Evil Queen Regina as they travel through a portal on the Jolly Roger in an effort to reach Neverland and rescue Henry." The pilot episode, originally released on iTunes in 2011, is available in both standard- and high-definition and can be downloaded until midnight tonight.

Like yesterday's offering, recordings from pop star Justin Timberlake's performance at this year's iTunes Festival in London, the "Once Upon a Time" pilot can be downloaded for free directly from iTunes. Users do not need to install the "12 Days of Gifts" app to access the content, a boon for users of older devices that do not support iOS 7, a requirement to install the app.

The "12 Days of Gifts" promotion runs from Dec. 26 to Jan. 8.

Apple's "12 Days of Gifts" app is a free, 64.7-megabyte download from the App Store.
