Canker sore at the back of my daughters throat?

My daughter, who is 11, mentioned this morning before school that her throat was hurting quite badly. I took her to school, and came home. I went to pick her up and about 20 minutes ago, she said "Mom. Look at this." Well, she wanted to look at her expander that she got yesterday afternoon a little closer. So she put the flash on her iphone on and she took a video of her mouth just to see everything, being the curious little girl she is! Then, she showed me the video. She had definitely noticed that there was a white/yellowish patch on the right side of her throat. I had noticed it immediately. I said "Hun is that where your throat hurts?" And she said "Yeah. That's why I came to show you. What is that?!" It was a canker sore. I told her to take an Advil and go lay down. She's never had strep throat and the pain is just above her right tonsil. The problem is, she started school 4 days ago. I can't take her out the 1st full week of school! If I have to, I definitely will, but she loves going to school! The orthodontists were having trouble fitting her expander yesterday. Does that have anything to do with it? But I don't want her gargling or swishing anything in her mouth, because its hard for her to keep liquids from going down her throat right now. All help is appreciated! Thanks so much! Oh, one more thing. Are there any remedies (besides liquids) that can heal it within the weekend? Should I take her to the doctor?

IPhone 5 Lock Screen for Android?

Yesterday I did something super dumb. I have an android phone (lg motion) and I downloaded an app called iPhone 5 lock screen so I could see what it was about. So I opened it, (so cool). And when I press my home touch key, it gave me an option to either go to my phone screen or the iPhone screen. And under it, it had a box that said make this my default screen. So I checked it and now I have an iPhone lock screen, home, panels, everything. And now i regret it and I don't want it anymore. If anyone knows how to uninstall an app from an iPhone, or better yet get me back to my Android setting please respond back A$AP. Thank you!

btw…

I have MetroPCS so I couldnt get an iPhone

My iPhone keeps disconnecting from Wi-Fi? - 1

I have no idea what could be causing this…
The only POSSIBLE, --POSSIBLE-- linked cause that I could think of could be me resetting the network settings on my iPhone.
Just about ever since then, my iPhone barely connects to my home Wi-Fi, when it does, it's very slow, and it only lasts for less than a minute at a time before disconnecting again.

Yes, for those of you that give the thick headed answers, I obviously entered the password to my network onto the phone.

How to activate my new (to me) Iphone 4S?

Okay, I have an Iphone 3gs. I just got an Iphone 4s in the mail today. All I need to know is how to get rid of the "no service" text at the top of the screen. That is all I need to know. I have looked everywhere, and am starting to get frustrated. I have even called on my 3gs, that didn't do anything at all since the pre programmed voice thought it was activated (I believe it was thinking that I wanted to activate my 3gs). Its not like I can call on my 4s since I need service. What is an easy and quick way to get everything working the way a normal Iphone would work.

Oh and if anyone knows how to get all your old pictures (without using Icloud) off my 3gs to my 4s, that would be great, but it is not top priority at this moment in life. Thanks.

Added (1). That is one problem I forgot to mention, I got rid of my landline because all of those stupid telemarketers. I will definitely take it to my local AT&T store. I just want to see if there's anything I can do before I make the effort to go there. I hate talking over the phone too, to one of those reps or whatever because I can hardly understand them one bit.

How long should an iPhone battery last?

I have an iPhone 4s that I bought this past January. My battery lasts roughly 3 and a half days with the odd couple of minutes of phone calls. And to check my phone periodically. Now is this normal for an iPhone battery when left on or should it be lasting longer?
