What update did you do? Most rom updates (both legit and hacked) will blow away everything.
Couple things to check...
Did she ever use activesync to sync with MS Outlook on her computer at home? if so, check out Outlook and see if her contacts and other things are there.
If she used an SD card... it's possible some of the things she used or stored are located there... Contacts and e-mails won't be, but other things like pictures and music might.
If she used it to sync with gmail or yahoo or any of those sites, it's possible the e-mails / contacts will be at the respective site.
Winmo has a file explorer, you can use to browse around the file system to see if you can find any of the missing pictures and whatnot.
