BB Bold 9700 :: Any Way To Get Saved Texts / Contacts Back

I was over at my sister's home. She decided to take a crack at guessing my blackberry password... 10 times. Ultimately she ended up clearing about 4 months worth of text messages, and contacts, the photos however remained unscathed.This lead me to wonder;

1. What is affected by a memory wipe.

2. Whether it's actually called a memory wipe, when someone enters your password wrong too many times.

3. Is there any way to get my contacts back?

4. Is there any way to get my saved texts back.Before I go on, I realize that this phone was and is designed specifically for business, I don't expect that there would be a way to get this information back, as that would defeat the purpose of a memory wipe in the first place.

5. How and where can I install the desktop manager? I've only been using my BB how it came out from the box because the CD included tends to freeze / crash my computer.

6. Why is it that the photos remain on the phone? 7. Before the memory wipe, my SIM card had enough space to hold tens of thousands of text messages, now after the wipe, and just another 10 - 20 texts, it constantly says "The SIM card is full." this is what got me HOPING, PRAYING, that somehow, my data was still in there somewhere.

Finally, thank you for taking the time to read through this, if you have an answer or a thought on any of the above, please feel free to post it. I need all the help I can get. (New to BB, New to forums, I might as well right "Lost" on my forehead and walk around this website.
