3. AVRCP controls are now enabled. This allows for bluetooth enabled accessories to control various iPod features.
4. Game Center – Social networking feature for iPhone gaming
5. HDR photos for iPhone 4
6. Ability to disable autocorrection
7. Ability to upload HD video straight from the iPhone to Youtube
8. Ability to rent TV shows from the iPhone

Excited?You shouldn’t.

A vulnerability in iOS 4.1 is allowing people to make calls on a nominally locked iPhone 4, users note. Passcode-protected iPhones typically block most actions unless a person picks Emergency Call and dials a genuine emergency number, such as 911. Circumventing this on the iPhone 4 can be done by entering a non-emergency number from the Emergency screen, tapping Call, then immediately hitting the lock button. The action brings up the Phone app, where people can then access a contact list or manually dial any number.

The issue is not unique to Apple hardware. Only recently, a similar flaw was discovered with the Motorola Droid 2 and Droid X. With those devices, restricted calls can be made through a combination of Voice Actions and holding down a search button. Other Android 2.2-based phones are so far unaffected.
