That surge sent iPod touch downloads up above iPhone downloads for the first time ever. Considering that teens and pre-teens are heavy on the app usage, Flurry speculates that a lot of those iPods went to younger users, who than ran to the App Store and started marathon downloads.
Overall, the App Store saw download increases of 51% compared to November.
There was good news for up and comer Android too: the Android market saw a healthy 20% bump in app sales, largely helped by sales of the Motorola Droid. A full 49% of Android app sales were for the Droid.
But Motorola can't celebrate quite yet; App Store downloads are still running 13 times higher than the Android market. With all the publicity over the iPhone, it's good to remember that the other device behind a lot of the momentum driving the App Store is the iPod touch. Who knows, maybe an iPhone OS based tablet will make the numbers even more impressive.
