IPhone 4S Can't Take Photo, not enough storage?

So I have had my iPhone 4S since March 2012. The last few months the space has been eaten up so quickly! It's only 16G, which I guess is a mistake since my last iPhone was 32G and I never had issues with it. I only have 2 apps - Facebook and Twitter, it says there's no space for anything else.
Every time I take a photo I must delete tons of old photos to make space - each time it makes me delete more and more just to take one.

I'm really sick of deleting all of my old pictures, as with my old iPhone I kepts thousands of my old ones on there, but now I have less than 900 because I have to! I also just purchased an extra 10 GB of storage but it doesn't seem to help much at all.

Please tell me a way to take photos or figure out my space issue!

I lost my iPhone in the snow. I think?

This might be a stupid question, but I've heard a lot of different answers to this and wonder if anyone might be able to give me a straight one.
I lost my phone on Saturday (iPhone 4s) somewhere between leaving my work and walking across the street to my car. I'm almost positive I had my phone in the side pocket of my purse, but after I brushed the snow off of my car I reached into my purse for it and it was nowhere to be found. I retraced my steps literally 5 times over and hunted in the snow around my car 4 separate times, searched my car and emptied out my purse and it's still missing. I also checked my work, and it wasn't there, so I assumed I dropped it in the snow. I lost it somewhere around 6PM on Saturday and it's now 12:04 PM on Monday. When I call my phone, it still rings and doesn't go straight to voicemail (like it would if it were dead). This sort of leads me to think maybe it isn't in the snow -- wouldn't it be water damaged by now/dead/shut down from water damage? Has anyone had an experience with their iPhone and snow? So basically, my main question is, after 24 hours if it still is ringing when I call it, what do you think the chances are of it actually being in the snow? I have hope it might still be alive hidden somewhere without any sort of water damage, not in the snow. If anyone could help me out that would be great.

*Also, I stupidly didn't install the find my iphone app and I'm really kicking myself for it now. I only got this phone about a month ago and never thought to do it.
