Everyone knows Apple has recently released iOS 4.2.1 to the public. I figured now would be a good time to post the direct links to the firmware updates. If you are currently JailBroken and update to 4.2.1 you may lose your JailBreak or Unlock at the moment.
If you’re wanting to test the Find My iPhone feature that is now part of iOS 4.2.1 (for iPhone 4, iPad and iPod Touch 4G) you can check out Apple’s website on how to setup Find My iPhone.
