Greenpois0n iOS 5 Untethered Jailbreak is Almost Ready[/h3]
World’s first convention of iOS jailbreakers ‘
MyGreatFest‘ was held yesterday in London. Some prominent people from the jailbreak community participated in the event including Jay Freeman aka @Saurik – the creator of Cydia, the key member of Chronic Dev Team Joshua Hill aka @p0sixninja, iFile creator Carstein and others.
The most amazing news at the event was brought by Joshua Hill who announced that Chronic Dev Team had found 5 exploits to jailbreak iOS 5 which is a record number of exploits for any iOS version. All of these are userland exploits which are not affected with any hardware release but can be patched with a software upgrade. These exploits already work on current hardware, have been tested on all iOS 5 betas and found to work perfectly. More importantly these exploits work with the iPad 2 as well.
Chronic Dev Team will be releasing
Greenpois0n to untethered jailbreak iOS 5 on iPhone 5 once they have the hardware in their hand but the untethered jailbreak is very likely to be released for iPhone 4, iPad 2, iPod Touch and other existing devices as soon as the iOS 5 is released. There are no promises made but having 5 userland xploits in hand, which have not been patched in any iOS 5 beta, is a great success and makes us believe that iOS 5 untethered jailbreak is not too far away.
iOS 5′s latest beta 7 is already available for
download and it can be jailbroken tethered with
redsn0w or
sn0wbreeze. It requires you to give a UDID to activate which is only available to iOS developers but if you jailbreak iOS 5 beta 7 with sn0wbreeze, it will
remove the UDID requirement so you can activate without a developer account.

Siri voice command system ported from iPhone 4S to iPhone 4 (video)[/h1]

Developer Steven Troughton-Smith has been working with
9to5Mac exclusively to port the iPhone 4S Siri voice command system to the iPhone 4.
Troughton-Smith was able to get the beginning steps of a full port rolling after installing the iPhone 4S Siri and Springboard files onto an iPhone 4. As you can see in the video, Siri’s interface loads up with all the features from the iPhone 4S implementation.
Siri on the iPhone 4 can recognize spoken commands in both the standard Siri view and the keyboard Dictation view. The only issue at this point is that Apple is not authenticating (obviously) commands to its servers from iPhone 4 hardware. The Siri port to the iPhone 4, at this point, also has the ability to speak back to the user. You may notice Siri and the iPhone 4 acting very sluggish in the above video. The issue here is not Siri, but is that a special GPU driver for iPhone 4 is needed; and it is obviously not included in the iPhone 4S binary cache – where the Siri files are located.
Perhaps the biggest news here is that we’ve determined that there is no technical reason for Apple not to allow Siri to run on the iPhone 4. The iPhone 4 hardware can support the Siri artificial intelligence system, as the A4 processor is said to be powerful enough. We are not entirely sure why Apple is making Siri an iPhone 4S exclusive but it could be due to special microphone support, or because the A5 may allow it to run slightly quicker. After all, Apple is the company who blocked custom wallpapers on the iPhone 3G because the animation is slightly slugger than the animation on newer iOS devices.
