Following up on last evening's rumor
, Apple has pulled the trigger and made its acquisition of mobile ad network Quattro Wireless official. A sale price wasn't disclosed -- $275 million is the popular number being thrown around -- but the company's CEO Andy Miller has been immediately elevated to Apple's newly-minted VP of Mobile Advertising position. In a news post on Quattro's site, Miller says that its products and services won't change "for now" -- but considering that it offers tailored advertising across a huge bounty of devices and platforms, we have to imagine Apple's long-term strategy is going to involve making this framework more of an App Store value-add for developers. Time will tell, but one thing's for sure: this is good news if (and only if) it either makes life easier on devs that want to offer awesome free apps or finally ushers in the era of free, non-carrier-subsidized, ad-supported smartphones that don't suck.
