4S constantly disconnecting from data; forced to reset

Ever since yesterday, my iPhone 4S has been doing this annoying thing where the data services will simply stop working. The bars or '4G' symbol don't disappear; they look the same as if I had full working coverage. However, anything involving data doesn't work. Spotify doesn't stream, Twitter doesn't refresh, pages in Safari don't load, etc. I don't know if calling and texting still work as most of the people I text use iMessage anyone, and I rarely call, but I know for sure that the data stops working. However, soft resetting the phone solves the issue... temporarily. I've had to do it twice today and once yesterday. I've had issues before where it won't turn off, it will immediately turn back on, and also where it will completely crash when I'm using a simple app like Twitter (freezes, screen freaks out, then takes me back to the lock screen). Could there be something wrong internally? I have dropped it a few times, but those caused damage of nothing more than a few light scratches. It's on the latest firmware (5.1.1), if that matters.

 

Anyone?

 

Can anyone at all help me? lol.

At this point I can barely use my 4S anymore, the data only stays connected for a couple minutes after each reset and after that it's nothing. Also the battery is skyrocketing down, I had it charging all night, then unplugged it for 2 hours (2 hours of literally NO use), and it was already down to 73%. I seriously wish these issues were happening a week ago because I was in Minneapolis by 5 Apple stores. Now the closest one is 3 hours away and I'm not driving that far.
