Can I backup my iPhone to a certain date(deleted videos)?

I went someone on Saturday, and had over 30 minutes of video. I then thought I would download iMovie, cause I wanted to mash all the videos together, and I had already bought iMovie 3 years ago, but hadn't used it in such a long time.

I put all of the videos on there. I then wanted to put the movie on my laptop. I knew that if I put it in my camera roll, then connected my phone to the laptop, I could do it, but my camera roll didn't have enough space for it, so I deleted most of the videos! And well you can guess what happened. You NEED the videos in your camera roll for them to be in iMovie, So I MESSED UP So BAD.

I didn't sync my iPhone before this btw:'( this happened yesterday, the day after I returned.

I thought the videos would have stayed in iMovie even tho I deleted them from my camera roll.

what can I do? It's an iPhone 4S and iTunes 7.4 I think.

How to take my husbands number off my iPhone?

I recently updated to the new iOS whatever it's called and me and my husband were just using my iCloud account and after I updated I noticed that all my text were going to him and all his were coming to me.

I accidentally locked my iPhone 5s?

I removed the passcode to my iPhone 5s so someone could use it for a school function. After I got my phone back I put a NEW passcode on my phone that was different from the one before it. I have Touch ID on so when I changed the passcode I kept the fingerprints. Now I can't recall my passcode and if my phone ever dies or has to restart I can't access it because Touch ID only works if you put in your passcode, "input passcode to activate Touch ID". I don't want to wipe my phone and lose all my data but if my phone dies or restarts I'm screwed! Please tell me what I can do and how to do it, explain very clearly too because I don't want to do one thing wrong and erase all my data! I currently have my iPhone connected to iTunes on my computer and everything I've looked at says I have to wipe my phone! I would remember my passcode but the passcode was a word passcode and not a simple number passcode. I really really really Really need this and I don't know how to remove my passcode and I just Really NEED TO REMOVE MY PASSCODE WITHOUT WIPING MY PHONE Thanks Please Help! That's all I need, I just need to remove my passcode without wiping my phone!
