Fancy a blue virtual keyboard for your iOS 7 device? If so, the appropriately named Cydia tweak BlueBoard may just be the tweak for you.
Once installed, users need to launch the Settings app and respring the device to get the tweak up and running. The tweak affects both keyboards within iOS 7, so that when enabled both the standard light keyboard or dark keyboard come with blue keys.
Currently BlueBoard is available in the BigBoss repository, compatible with iOS 7.
As with all tweaks, of course, you’ll need to jailbreak your device in order to take advantage.
