IPhone problem? What happened?

So, about a year ago I stopped using Omegle on my iPhone. Now, it won't really work. The buttons either don't work or don't go to a chat.

Iphone app that can say anything you type

I recently went to the doctor. Turns out i have strep throat. I live with my family and i'm trying not to talk to them so they don't catch it too! I was wondering if there's an app that can say anything that i type so i can talk to them that way?

Is my iPhone5 worth trying to fix?

About a month ago I dropped my iPhone 5 in the pool. It was in there for no longer than 5 min when I got it out, and immediately opened it up entirely to try and dry it out. A couple days ago I plugged it in for the first time since and after a few minutes the sound came on like it was turning on, but the screen wasn't working. If I unplugged the charger and plugged it back in, it would make the sounds that it usually makes at these times, but still with no picture. Is it worth a try to replace the screen or is it shot?

Can I use Wi-Fi app on old iPhone not in service?

I'm considering sports video cams that use Wi-Fi apps as the best way to control the device. I have an old original iPhone that isn't in service, but I have Wi-Fi in the house (where I'll be using the cam on my musical instruments).

Will it be possible to do this? I'm completely uneducated on these phones. I only have this phone because it was given to me.

I lost my receipt what should I do?

My mom bought me an iPhone 4 for my birthday from Walmart. When she bought it they said that she can return it within 2 weeks. When I was checking the phone out, I noticed that the phone was Verizon and I really don't want that. We lost the receipt. My mom told me that we can try exchanging the iphone 4 for a 4s. I'm just really wondering if I can exchange the two phones without the receipt? What can we do?! I can't have Verizon because my mom doesn't like the contract. So overall my question is… Can we change the iphone 4 to an iPhone 4S without the receipt (my mom used her credit card to buy the iPhone). Please help this is very important! Please keep your answer simple but in a lot of detail!
