![Unlock For iPhone 3GS, iPhone 3G On iOS 4.2.1 Released [Updated]](http://www.iphonehacks.com/wp-content/themes/iph/timthumb.php?src=http://www.iphonehacks.com/images/10-Mar/iphone-unlock.jpg&h=129&w=194&zc=1&q=100)
iPhone Dev Team has released the eagerly awaited unlock for iPhone 3G and iPhone 3GS users on iOS 4.2.1 just as they had promised.
Apple had patched the exploit that allowed users to unlock their iPhone in iOS 4.1 released on September 8 so it has been a long wait for users who wanted to software unlock their iPhone to use it with any carrier.
Find My iPhone – the MobileMe service that lets users track their lost iPhone is now offered free with the latest iOS 4.2.1 update. This feature is available by default on the latest iOS models like iPhone 4, iPad or iPod Touch (4th generation).
However, if you are a user with an older model, it is possible to set up the location tracking feature on your iDevice provided you also have access to one of the newer models.

Looks like its turning out to be a bad time for all you iPhone 3G users out there. After the removal of support for Game Center for the device in iOS 4.1, its the turn of AirPlay to meet the same fate.
Folks over at 9to5Mac are reporting that Airplay support has been removed for iPhone 3G from iOS 4.2 GM that was released to developers last week.
