Earlier today, Apple pushed out a couple of software updates.
The first, and the one that’s been anticipated for a while, even going back to before iOS 4.1, is iOS 4.2. Technically it’s 4.2.1.

* AirPlay – stream videos, music, and photos to AppleTV or AirPlay-compatible speakers and receivers, such as AirPort Express, over a wireless network
* FaceTime improvements
* Safari – find text on the web page
* Notes – new fonts (yay!)
* Can now set custom tones per contact for SMS/MMS text messages
* improved parental controls
* Import .ics files into Calendar
