How to find your iphone with find my iphone app?

I have the app installed on my iphone but my iphone is offline. I have my mac with me which is online. How does find my iphone work? I have it locked and the display message says to call me at a different number when found. Do I get an email or phone call when someone is trying to use it though?

PERFORATED EARDRUM DISCHARGE BUILD-UP?

My eardrum ruptured because of an ear infection two days ago. After, it drained for a while and then stopped. (But from what I've heard, it should drain longer than that.) Also, my ear stopped hurting directly after the perforation, but then the pain came back a couple of hours afterward. After school today I used a couple of mirrors and my iPhone flashlight to see for myself what was going on, and there's a huge wall of liquid-y pus/discharge that is just sitting there in my ear canal not going anywhere; I'm thinking this is the cause for my extra pain. So, how should I get it moving and out of my ear? It seems thick. My mom and I were thinking of using a bulb to lightly suck out what is sitting on the outside and hopefully start up the flow again. However, we figured it be best to find out more before we went in and made things worse. (Also, please don't mention going to/asking our doctor because that's a rather generic response, and everybody already knows to do that. We're hoping for a cheap, do-it-ourselves way before resorting to that.) HAS THIS EVER HAPPENED TO ANYONE BEFORE?

AT&T Claims 3G in my area but I don't get any?

I have the iPhone 5s with AT&T and I think that I'm going to be upgraded to 4G soon from my current 2G. I was looking on AT&Ts website to find any info on the 4G upgrade but then found out that they claim 3G in my area. I have never gotten 3G with AT&T anywhere at all and everyone I know with iPhones and other phones get 2G service. Why is this and is there a place that I can find out what AT&T is upgrading?

Is the Iphone worth waiting for and buying when it comes out?

I have an iphone 4 still, it works but looks dead. Its got crack all over the front and back and pieces of glass fall every now and then, but still works fine. I've been waiting for the 6 to come out but wondering if its worth buying or should i buy another phone? If so, any recommendations?

Is the digital age becoming too dangerous?

Phones track our locations, know our habits, bank details, emails, contacts, intimate secrets we discuss with friends and family. In essence, they know where to hit us to make us hurt.

"The 21st Century is a digital book." All it takes is for someone to read our book and voila. We're at their mercy. Now, you could tell me that my information is encrypted or protected but the majority of the world has no idea whether that's true or not. Throwing some random words at us that sound like protection is a placebo at best.

The iPhone and pretty much the rest of the digital age is becoming a dangerous tool. As soon as it falls into the wrong hands, it's a new form of totalitarianism. I'm all for advancements in technology, but the world needs greater contingency plans and safety measures to ensure that our data is safe and free.

If the NSA or police or the like can spy on a criminal - find out his location, his habits, who he knows, etc. - who's to say they won't do that to you or me for saying or doing something they don't like. And get away with it with impunity.

What bothers me is not the capabilities of these technologies. What bothers me is how easy it is for someone to abuse their capabilities.

So what do you think?

Can I still exchange for the black one? It has Only been about 9 days

My Iphone 5S screen doesn't work? - 1

My Iphone 5S screen doesn't work?

Added (1). I recently cracked my phone screen and so after doing some research I decided to try and fix it myself as people had said it is quite simple and a lot cheaper than getting it replaced. After replacing it however I have discovered that the touch screen won't work at all, all the other buttons do just the screen won't respond to anything. I was wondering which part of the Iphone contains the touch screen chords and whether I can replace them or is it a faulty screen?
