Putting an icon on your iPhone home screen allows you to quickly access a program or application (app). That’s exactly what SiriBoard cydia tweak does. Developed by FreeManRepo, SiriBoard tweak launch Siri assistant directly from your iPhone SpringBoard without straining the Home button.
SiriBoard Cydia tweak can be downloaded and installed via Cydia store under BigBoss repo for free. Once installed, Siri icon will appear on “HomeScreen” and as soon as you tap on this icon, it will open without need of pressing the Home button. Before you install SiriBoard, your iOS device must be running on jailbroken iOS 5 and above. If you haven’t, then you can use Absinthe tool to jailbreak iPhone 4S or Redsn0w to jailbreak iPhone 4 or iPhone 3GS (Siri must be installed via Spire Tweak).
Few days back, the same iOS developer released similar tweak LockAssistant (available under bigboss repo), for opening Siri directly from the iPhone lock screen. Both of them work great and don’t have any sort of incompatibility issue. If you have QuickSiri installed on your iPhone, SiriBoard will launch Siri in full-screen.
The downside of SiriBoard tweak is that the icon’s interface is completely different, when compared with stock icons which are normally square with rounded corners. It is just a scaled image of Siri icon with transparent background and it looks odd when available on SpringBoard. Otherwise, the tweak loads Siri interface even quicker than you do by pressing down the home button for few seconds.
[Update 1]: Developer has added a new icon, which gels well with other icon available on your iPhone Homescreen
