About a week ago my camera would not start and i was constantly getting a 'camera not responding' message.

i did a hard reset through terminal and now things have gotten worse.
Here is a list of errors I am getting:
1 - notes will not save in note application.
2 - cannot down load email or mms attachments (seems like mime types are not associated anymore).
3 - email does not send.
4 - email does not receive on specified frequency (seems like it might retrieve once a day, and even forcing a refresh does not retrieve current emails). i removed qmf file already and that send to help for a brief period but not anymore.
5 - contacts not updating through online services (facebook, etc).
6 - camera worked for a few days but am now getting 'camera not responding' message again.
7 - my accuweather widget will not stay on.I uninstalled and tried to re-install and and i get an error that the package can't find dependencies.
8 - when i did a hard reset i lost all my contacts and messages.
9 - I can't save bookmarks to desktop.
10 - The desktop universal search does not work.

i don't have many apps installed and haven't downloaded anthing in quite a while. there may be more errors but i haven't seen them yet. any suggestions on how to restore device or find out what got corrupted and how to fix it? i can reflash but would rather not.

thanks
