My Twitter won't let me log in

Basically, I just reached 2, 000 followers on Twitter, but the next day when I went onto the app on my iPhone it said I had 0 followers that I was following 0 people, my picture wouldn't show, my tweets wouldn't show, the people I follow's tweets wouldn't refresh and when I signed out and try signing back in again it says: your username and password can't be authenticated. Double check that you entered them correctly and try again.

This had happened to my account before and once my recent one wouldn't let me back in, I decided to make another one but after a few minutes it did exactly what my others did.

Please someone help me get my account back? Any tips on how to do it? Please?

I says my iPhone password is wrong but I'm certain it's correct?

I went on my phone using my regular password (word password, not the 4 numbers one) and it was working fine but a few hours (2 or 3) later I went on my phone and it said incorrect password. My phone hadn't left my sight, so I'm very confused. 1. How could this have happened? 2. How can I get into my phone without restoring it because I really don't want to loose everything, I've had this phone for almost 3 years. It's the iPhone 4. I'm so worried.

Is she lying to me about not having Internet?

Okay so me and my friend had a little fight but she blocked me on facebook, she says that she will unblock me but she has no internet. What she doesn't know that she's friends with my sibling and I had a look on her facebook and it said something like "about an hour ago in Geelong." Does that mean she has internet? She has an IPhone and uses facebook at school so is it free facebook? And can you unblock someone on your phone facebook? Also one time we had to get a project in and one time while walking to class I asked her how she was going since I had finished and we only had a week left to finish and she said that "I only got half of it done." I asked her "some by the internet?" and she said "yes." Then later she said that she does not have the internet but I said nothing. Is she playing me or something? Is she lying about it? Because on facebook it show's nothing about Via mobile, please help I have to know.

What to do about my water damaged iPhone 4?

So on Thursday I had soccer practice and my phone got water in it. I could see it in the screen when I hit the home or the lock button and it was very dimly lit. I later noticed that the lights at the top under the screen were going out and there were 2 working while one was flickering. I decided to put it in rice because everyone said that worked. The next day (Friday) the water had gone away a bit but the screen was darker. For some idiotic reason I decided to take my phone out and use it all day which resulted in my screen not working anymore. I'm still recieving texts and what not but I can't see anything.
I don't have my pictures or contacts backed up to iCloud so my question is,
Can I still save my iPhone if I take it to AT&T or will they have me buy a new one? Also, if I do just get a new one will they be able to transfer my contacts and pictures?

Why should working people have to pay for the healthcare for those on welfare?

Everyone has hard times by why should others have to pay for years for healthcare for people who are just too lazy to work? The same people who have Iphones but get free healthcare. Why should those on welfare get more benefits for having more kids they can't afford? Certain Medicaid insurances also reimburses nothing to health care providers so the providers foot the bill. These people consume healthcare because they are obese and have health problems too. Many of them act as if they are owed free healthcare. But others are paying thousands of dollars for their medications, treatments, and doctors visits couldn't they at least do some community service? How is that fair?
