I’ve always wanted this feature on my iPhone and after trying all those annoying no-good free and paid apps on App Store, I eventually gave up looking! But now, a brand new Cydia tweak called Click2Call seems to have solved this problem allowing you to create springboard icons / shortcuts to your favourite address book contacts without using the old Safari bookmark workaround used by most App Store apps. Instead, Click2Call uses MobileSubstrate to make the calls and allows you to create springboard icons for both a phone number or a FaceTime contact.
Check out the following video of Click2Call in action:
You can grab Click2Call for $1.99 on Cydia Store via the BigBoss repo!
