BB Software :: Lost Photos Whilst Doing A Backup On Old Bold?

I backed up my old BB Curve last week before I went into town to get the new BB Bold.When I came home I did the switching devices thing on my computer with both phones.They both have separate memory cards in but the Curve had all my old stuff; camera pics, voice notes and vids.Since backing up the Curve or switching devices to the Bold all that has disappeared!I thought that was the whole point of backing up something was to not loose it all, but it seems to have done exactly that! I can only assume that all of those were saved on the memory card not the phone, but I'm not sure, what is the default setting, and why it has disappeared in the first place!
