Siri is probably your favourite feature of the iPhone 4S and we don't blame you, its absolutely fantastic. Amazingly, now there's a way to make it even more exciting. This post will tell you how to launch Siri without pressing Home button.
Siri on iPhone 4S is amazing. It takes commercial artificial intelligence to a whole new level. All you have to do is speak with Siri and it will do a variety of tasks for you, including but not limited to reading and replying to emails, setting alarms, taking notes, displaying the weather etc. It really is one of the major differences between iPhone 4S and iPhone 4.
To launch Siri, you need to press and hold the Home button. However now there is a way to launch Siri without pressing Home button. Its a nifty little jailbreak tweak called Hands-Free Control. This tweak is always on and runs in the background. Simply say 'Siri' out loud and your virtual voice assistant will be all fired up to help you. Apart from iPhone 4S, this tweak will launch Voice Control on iPhone 4, iPhone 3GS, iPod touch 3G and 4G because they don't have Siri, but you can install Siri on non-iPhone 4S. Follow our detailed guide on how to install Siri on non-iPhone 4S devices.
Now we know that currently it is not possible to jailbreak iPhone 4S. To get the full low down on that, check out our extensive write up on iPhone 4S untethered and tethered jailbreak possibility. You would be able to use this tweak on your iPhone 4S as soon as a jailbreak for it is available. An iPhone 4S jailbreak has already been demoed on video and its possible that a release will be coming in the next couple of months. In the meantime, you can download and install Hands-Free Control on your jailbroken non-iPhone 4S devices and say Voice Control to launch the relevant function on your device.
Hands-Free Control is intelligent enough to filter ambient noise from a command, regardless of the fact that it always runs in the background. You can manually adjuste the sensitivity of keywords from Settings.app. Hands-Free Control is available for $1.99 from the BigBoss repository in Cydia.
For now, Hands-Free Control is only useful on non-iPhone 4S devices. However it is possible that a fully functional Siri port for other iOS devices will be released soon. Many developers are extensively working on it and one can be certain that there will be a significant breakthrough soon.
Obviously to use this tweak on your device, you need to jailbreak it. Follow our detailed guides on how to jailbreak iOS 5 tethered using redsn0w.
