Download iOS 4 Firmware for iPhone and iPod Touch

Apple has released the iOS 4 firmware for iPhone 3GS, iPhone 3G and iPod Touch 3G and 2G along with SDK 4. On Moday, June 7th Apple renamed iPhone OS 4 to iOS 4. iOS 4 firmware Build 8A293 is now available to developers enrolled in the iPhone Dev Program masses. iOS 4 Final will be released to masses in a couple of weeks.

iOS 4iOS 4 brings a lot of new features for both developers and users as well. The iOS 4 firmware is build 8A293 and iOS 4 SDK is build 10M2262. iOS 4 is not available to general public. However if you still want to give it a shot and download iOS 4, read the warning below and scroll down to find download links.

WARNING: Jailbreakers and iPhone unlocker MUST stay away from iOS 4 until the dev-team or someone releases new jailbreak and unlock tools for iOS firmware. iOS 4 requires iTunes 9.2. Updates will be posted at the bottom.

NOTE: iOS 4 fully supports iPhone 3GS and iPod Touch 3G but in iPhone 3G and iPod Touch 2G some features like multitasking won’t work (+1 reason to jailbreak). Apple has discontinued firmware updates for both iPhone 2G and iTouch 1G. Apple has also announced to release iOS 4 for iPad later this year.

Do you have a developer account?
Or is that the method described in the article does not require a developer account??

Thanks!!!

iPhoneHeat July 11, 2010, 5:37 pm

it’s not a zip that you extracted.. it’s a direct link to IPSW..
use Firefox chrome or IE to download it
safari often extracts IPSW
