Hello, I decided to register at Maemo developers web-site as a last resort measure

Briefly, I have been a Nokia customer for more than 8 years with my recent phone N900 bought right after its release in Russia in January 2010.
I have never experienced any problems with this phone until recently, when I went to the USA and switched on this phone - the touch screen immediately stopped working. Upon my return to Moscow, I called Nokia hot line, applied to local Moscow repair & maintenance centers (authorised by Nokia), however, the response that I got was that the problem is not about the touch screen, but about the operating system and they cannot do anything about it to return the phone to a normal working mode.

The problem is that I have lost all the data - the address book, messages, notes, photos, everything. I have never made back ups for my Nokia phones.

Can you please advise if there is at least a little chance to retrieve the data from the phone and if yes, how can it be done?
Would be grateful for any response.

Best regards,
Elena
