Introducing HackCenter. Available soon on the Cydia store, this hack allows you to send any score that you want to Game Center, and it works with every game. There’s no ETA for the hack, but we will keep you updated. Stay tuned…
Later edit: From the dev: ‘Due to the overwhelmingly negative response of HackCenter (GameCenter hack), I will not be releasing it to the Cydia store’
