Iphone 3GS voice memos disappeared after IOS6 update?

After having updated to IOS6 I noticed that the voice memos I had on my phone had disappeared. The back-up files did not show any trace of what I was looking for either. This was months ago and I thought I totally lost some of my voice memos. Now, with the upgraded version of iTunes, I see those memos in iTunes as long as my phone is connected to my PC (under iPhone/ On This iPhone). I can play those files however that's all I can do. I can't see them on my iPhone nor in the library of iTunes. I downloaded this program called iExplore; I see most of my missing voice memos there but still not the files that I'm looking for.

I would really appreciate it if someone could help with this issue.

Thanks

Added (1). My question is: is there a way that I can finally locate these files and have them on my PC.

Can I jailbreak my iPhone 4S? - 2

I used to have my iPhone 3GS jail broken a couple years ago during Christmas (when it was as simple as going to jailbreak.me ans sliding!) and I had this awesome Christmas theme that I fell in love with. I want to use it again this year, but the stuff I found online is IMPOSSIBLE to understand!
I'm running iOS 5.1.1, btw
Can I jailbreak? If not, can I downgrade my iOS to a previous version to jailbreak?
Thanks!

Added (1). Should've made myself clearer… I meant HOW can I jailbreak my iPhone.
I don't think Apple is going to help me out when jailbreaking is looked down upon…

Dropped Iphone 5 in water, what do I do?

My girlfriend dropped her iphone 5 in the toilet, it had a defender series otterbox on it and only got the bottom a little wet. She turned it off immediately and we put in in some rice to let it sit. Is there anything else to do? Also, if this does not work what is the best route to go to get it fixed/ get a new phone? She has Verizon but does not have any insurance on it. Was thinking about getting insurance then waiting a few days and then taking the phone it or saying it got lost, would this work or is there a certain number of days you have to have the insurance before you can file a claim?
