The app doesn't allow me to switch language on my E71, so I even can't fill in the login form. My default lang is Russian. Failing to fill in the login form renders the app totally unusable.
Steps to reproduce:
1. Choose the phone language (and the default input language) containing no Latin letters.
2. Make sure that it's non-English language currently selected.
3. Start the application for the first time.
4. Choose «Ovi account»
5. Try to fill in user name. It writes your local alphabet letters, not the Latin ones you allowed to write your account name with.
6. Try getting Language menu with Fn+Space. It just inputs spaces.
7. Try to install third party language switching app like Lang Switcher from http://arok.org.ru. Sadly, it doesn't work either.*
8. Become sad.*
