Apple is setting up a new Manhattan office for its iAd sales team, several sources claim. The space is said to be located near Union Square, and should replace or complement an existing office in SoHo. The latter is actually a former home of Quattro Wireless, which Apple acquired for $275 million in order to found iAd. The SoHo office is believed to be too small, however, never meant to hold more than 30 people.
