Help Change of operating Language

[valc]

Hey! I am considering to get a Slider from Germany, but the problem is that currently its operating system is in German and it doesn't give any other choices?

At the moment it runs with Honeycomb 3.0.

Would anyone have an advice how the language can be changed? If upgrading of the OS would "open these doors"? or should I try MoreLocale app?

Thank you very much in advance for help!
