Add a 5th Row to your iPhone Keyboard[Cydia Tweak]

Now with a simple Cydia Tweak called as 5th Row Qwerty Keyboard, you can add a 5th row of Numbers and Symbols to your iPhone Keyboard.

This modification is achieved by using a Winterboard theming feature for file substitution. You must first activate the newly added theme from the Winterboard configuration in the Settings app. This has to be done before you can view and choose the Optimized keyboard layout from Settings.
After you install this package, please use Winterboad to apply the them.
Then, go to Settings > General > Keyboard > International Keyboards, Choose English ( or English (UK) )> 5Row.

The app is available on the Cydia store for just $0.99
