Some apps won't work with my data?

I have an iPhone 4s and when IIm out of Wi-Fi range and turn on my data some of the apps I did not have on at first to save data usage, do not connect when I turn them on. For example, when I try to use my Bank of America app, the app is on with my data but it still says "network unavailable, search for Wi-Fi or try again later." This does it with some other apps. This happened to me with my iPhone 5s but I do not remember what I did to fix it. Someone know what's wrong?

Dropped my iPhone is it okay?

I dropped my phone in publix just about less than 20 minutes ago. I have a case on my phone that protects the back and makes it pop out in the front so it's hard to get scratches on it. I picked my phone up and noticed in the left top corner there was ( it looked like liquid?) in the phone. But I haven't gone anywhere near water and didn't see it until after it dropped. My phone kinda did a flip when it fell, and after a while it looked like the inside of it had little scratch marks? Will it fade or stay. I think it's starting to get better but will it leave a mark?
