I have had the pearl since march

I had received another unit prior to this one but it was a mess and concensus was it was a problem with the bberry itself.
I had a problem with a 8 gb card with the unit I now have , it worked then it woudn't.((now that card does not work at all nowhere)) but I am using a 2 gb card and that is working fine

attached picture from my blackberry.I love all its features and it's more of a gadget than a phone lol.. but how i love sending on the moment photo emails and that brings me to.. my problem
My problem now is somehow i must of messed up my adress book. It always shows empty and I can not find any previously added contacts and can not save any new ones? in the adress book

any clue?
I can call and send emails to the people I had in the adress book as they come up when i type the letter of the name, so they are in there somewhere.I know I tried to group them as email but I cant find that either ..
I will keep looking but I'm hoping someone can help me
happy
