Hi everybody, this is my first und hopefully last problem with my iPad 2 (already updated to IOS5). Everything has been working fine for me for the past two months. Today, the app store showed me there was an update to install, so when I tried to do so, I was prompted to enter my password (as usual), but when I confirmed, App store quit and threw me the following message (in German): "Ein unbekannter Fehler ist aufgetreten.", which means "An unknown error has ocurred.". Memory is not full, I still have > 30 GB spare memory. I have turned off and on the device, but without luck. Any idea how to solve this problem? Thanks!
