Thank you for your help. I don't know what i did but the phone is working again.
I had to install again the OS (twice!) but at the end i solved the problem. Lucky i've got all my contacts and agenda in my Lotus Notes and with 1 replication everythin was in place ready to use.
Bad luck yesterday when i had to use another phone without bluetooth and i was caught by the Police talking over the phone while i was driving ....... 120€ and a ticket!!!!
