The original HTCLock tweak has been on the Cydia store for quite some time and has managed to rake up thousands of downloads from those who wanted to tweak the iOS lock screen to have a little bit more of the HTC Android flavor in it. Implementing the highly regarded HTC design on the iPhone and iPod touch obviously proved popular as it changed the default behavior and added the option to invoke a number of apps without having to unlock the device first. The same developer has now continued on with that tweak and released the HTClock Pro version that bundles in additional features and enhancements.
