Using Siri is absolutely a very inspirable thing to do on iPhone. If you have been using Siri for sending text message or other thing then this time you can tweet with Siri. Of course there is no way that you can do it with the default setting but with help from Cydia tweak, you can do it.
Mentioned by Tyler_nettleton Aka InfectionFX, a new tweak on Cydia is marked as coming soon. This tweak is called Sireet. With this tweak, you can tell Siri to send tweet to your Twitter account. This tweak is expected to be available for free.
If you are using iPhone 4S, then you should not have problem but for older idevices, you need to install Spire for Cydia for Siri.
