You’ve seen EzDecline to reject incoming voice calls, here’s another tweak that will allow a user to quickly reject an incoming call with a swipe of a finger to generate an automated SMS to the caller notifying them of your availability.

Go ahead and search for “I’m Busy SMS” in Cydia. You’ll have to scroll down the search results a bit as it doesn’t appear at the top.

There are no additional icons installed onto your Springboard, and everything can be configured from within the Settings.app

The tweak can be activated for only certain numbers, enabled or disabled, and also send a custom message in the SMS reply. When a call comes in you cannot answer, simply swipe:

It’s a great tweak, and for only $2.99 in Cydia. Never rudely reject an incoming call again! Unless you want to of course.
