After updating to iOS 5.01 the keyboard wasn’t shown anymore on my iPad2. This happened in all applications except Cydia.
I remembered that I had installed the (excellent) application 5-Row Keyboard for iPad which shows the numeric keys together with the QWERTY keys (in a 5th row). I also remembered that this tweak didn’t work in Cydia so I assumed that the tweak was incompatible with iOS5.
After uninstalling via Cydia the keyboard worked fine as well but I really miss the 5th row…
