We've already shown you how to hide the Ping drop-down in iTunes, but for many folks that wasn't enough — they wanted all evidence of Ping removed from iTunes' interface (and who can blame them?).
Lucky for us, Apple just pushed out an iTunes update that adds Apple TV AirPlay, support for the as-yet-released iOS 4.2 and other stability improvements — as well as a new checkbox (under "General" in Preferences) that allows you to disable Ping (hallelujah). Hit up Apple Software Update to grab the the new version.
