At Apple’s September music event, the company announced iOS 4.1 for iPhone and iPod touch and also previewed iOS 4.2 for iPad.
iTunes 10 and Ping were announced.
Ping is a social network for iTunes users to replace the need for Google Buzz and Twitter in our lives.  It may also be a Pandora rival in that you can see music recommendations based on your listening and buying habits.
They announced the following hardware updates:
iPod Nano
iPod Touch
iPod Shuffle
Apple TV
iOS 4.1
All bugs have been fixed!
That includes the proximity sensor on the iPhone 4, Bluetooth bugs across the iPod touch and iPhone, and lastly the much talked about iPhone 3G performance issues have been fixed.
HDR
iOS 4.1  also provides a new feature called High Dynamic Range Photos (HDR).
HDR is a new camera-based feature where the device camera improves the colour range of the photos you take..
HD Video & Game Center
iOS 4.1 will give us HD video uploading over WiFi to YouTube for example and also the new Game Center.
Apple’s Game Center is like Microsoft’s Xbox Live where users can play multiplayer games and be matched against anyone of similar skill in a particular game.
