Greetings for the long waited devices

. I'm really interested in buying 903. So I have couple of questions:
1.Do you deliver to Bulgaria?
2. Does it come with full Cyrillic support /Bulgarian and Russian/ or we should wait for firmware?
3. Do I have my 7 days /to return it in case of unsufficient performance or something like this/ ?
4. What am I doing in case in device multifunction during guaranty period?
Thanks
