Apple has released the latest operating system — iOS 4 for iPhone 3G, iPhone 3GS, iPod Touch and iPhone 4 at June 21, 2010. The iOS 4 for iPad will be available later in September 2010. Jailbreak iOS 4 should be coming soon, too.
Update: Here you will learn how to download and install Apple iOS update manually, bypassing iTunes unstable download server. This tutorial works on iOS 4.0 and above.
How to install iOS 4 using iTunes
- To install iOS 4, you simply connect your iDevice (iPhone/iPod Touch) to your computer.
- Launch iTunes, select your iDevice under Devices then click “Check for Update” button.
- iTunes will download and install iOS for your iDevice. Do not disconnect your iDevice until the update has finished.
- Your iDevice would be restarted after installation and… Walla! It is using iOS 4!
Note: Before you install iOS 4, make sure your iTunes has been updated.
If you have a bad connection like mine, you might want to download iOS 4 via a direct download link. It is faster and resumable.
