Is there anyway I can retrieve a lost (wiped) love letter from a deceased friend?

I got a new blackberry. My new blackberry has a love letter that a deceased friend wrote to me on it.
I used Blackberry Link to restore the new blackberry, not knowing it would wipe what was already on the blackberry, totally replacing everything with my old settings. I assumed it would simply add to my new blackberry, not alter it entirely.
The letter was saved as a note in the Remember application.
I cried for hours when I realized my love letter was gone.
Someone please, help me. Please..
Please help me get it back.

Unless you did a back up , or saved it to your sd card, I'm terribly sorry to say you have lost it.

Sorry, pretty sure it is gone. I'm assuming you did not back up since you had that letter, or you probably would not be here asking how to get it back.

I am deeply sorry for your lost, issue happened to me in a occasion, without my friend actually physically died though.

I would say it is possible but unlikely your file still exists on the phone. If you have stopped using it and turned it off I think there is a greater chance the file has not been over-written.
If you don't mind spending some money you could contact a professional data recover service that recovers data from wiped or damaged hard drives. I've never used such a service so I wouldn't know what to recommend.
