One of the most useful Cydia apps I've downloaded recently is "5-Row-Keyboard".
It works with Winterboard on jailbroken iPhones and gives you an extra row of number or symbol keys on the device's inbuilt keypad.
It makes typing much easier.
It was released recently in English-UK and English-US. And now the developer has released a version with a German QWERTZ keyboard.
It costs $1.99 in the Cydia App Store and needs iOS4 or above to work. It won't work on iPads.
