Apple turns iOS 'PC Free' with OTA updates and wireless sync

Love your iPhone, but hate all of the PC-based tethering it entails? Apple has some good news: the company is taking its "post-PC" stance a step further, letting you activate your smartphone straight out of the box without syncing it to a computer. Also big news is the addition of over-the-air updates, which will let you receive changes without plugging the handset in. And some big news for music fans: users will be able to sync their iTunes libraries over WiFi connections with the update.
