Apple iOS 4 Update Jailbroken Within Hours Of Release

Apple’s latest iOS 4 update has been jailbroken within hours of its release, technology news website The Inquirer reports.

The Cupertino-based iPhone maker had released the software update for its existing iPhone operating system on 15 July, claiming it would rectify the antenna issue that has plagued the iPhone 4.

Apple had said that the poor reception was caused by a mistake in the algorithm used to display reception bars on the device.

The software update has been cracked by the iPhone Dev Team, who said: "You can use this redsn0w from June to jailbreak 4.0.1 on iPhone3G. Just point it at the 4.0 IPSW (the public one, not the developer GM one).”

The group also stated that the mobile operator unlock can be obtained using its ultrasn0w application.

Apple is set to hold a press conference later today at its Cupertino campus to discuss the iPhone 4's antenna issues.
