I think you may have just hidden it!

Press menu and select "Show All"

go to your picture folder/select menu/properties then unclick hidden

Who is your carrier? Try to either calling them or log in to your account if thats a possibility. All your contacts should be saved on your profile.

All you have to do is go to the blackberry downloads page located here

And download the Blackberry Desktop Manager and the Latest software for your Handheld and you can upgrade you phone and reinstall all the applications without losing any information.

I'm sorry to say that it is likely completely gone.

I've never heard of a Blackberry recovery service. Perhaps send an email to RIM (Research In Motion) and ask? If your BB came from your company (as opposed to a personal plan) perhaps your IT department can help?

One other thought: If you are using the BB at work and it's hooked up to a Blackberry Enterprise Server (BES) then at least your email, calendar and address data _might_ be stored on the server. Ask your IT department.
