Apple made a number of tweaks to the user interface in iOS 7.1.
Phone was one of the apps that received quite a bit of attention. For example: the long rectangular buttons were replaced with circular buttons.
If you’re still on iOS 7 because you don’t want to lose your jailbreak, but like the iOS 7.1 style buttons in the Phone app, then install this new tweak called Button4Phone.
It replaces the rectangular Call button with iOS 7.1 style circular button. It also removes the Add to Contacts text, and replaces it with a “+” icon that allows you to add the dialed number to your Contacts as you can see in the screenshot below.
The tweak doesn’t change the “Decline” and “Accept” buttons which were also replaced with circular buttons.
Here’s a video walkthrough of the tweak via our YouTube channel iPhoneHacksTV:
Button4Phone is available for free on Cydia. Let me know what you think in the comments.
