My iPhone 4s Doesn't show any signal bars yet still has 3G?

I have tried everything to fix it from restoring to resetting network settings, I have tried the SIM in another phone and the SIM works fully, however the other phone wasn't an iPhone…
The signal bar looks as follows '_ _ _ _ _ VodafoneUK 3G' may I add that I'm on a TalkMobile tariff, I have had the iPhone for months now, and all of a sudden it has just done this, and it does it everywere!

Deleting all of my social media?

I'm 15 and I decided to delete/deactivate it all. Facebook, Twitter, instagram, tumblr, everything. I was so unproductive since I started using Twitter especially. I got my first B after I started using Twitter! Which sounds weird, but I'm generally a straight A student. I deactivated everything yesterday and I keep getting these urges to tweet everything I'm doing like I use to. I changed the passwords to a random combo of number and letters, so I couldn't try to reactivate even if tried to. I just have so much free time now I don't really know what to do? How do I stop automatically grabbing my iPhone after something happens so I can tweet it? I know it sounds really pathetic.

Iphone 5 dilemma, read description?

I bought an iphone 5 last year in november (i also got extended warranty) it was good for a few weeks and then the home button stopped working, so i went to the apple store and they gave me a 'new' iphone 5, i didn't even look at it, as soon as i got it a put it in its cover.about a week ago i got a new cover so when i took the cover off my iphone 5 (black) i noticed there were many scratches on the frame of the phone and even a couple of dints. So i went to the Apple store today and the lady refused to give me a new one even though i have extended warranty, she said i shouldve came when i got the phone, but i didn't even look at it because i put it straight into the cover when i got it and only noticed the scraches very recently.
i thought she was legally required to give me another one having read the apple terms and conditions about iphone 5 warrenty, the folowing is specificly stated in the terms of service in the first paragraph on the apple webside:
Our goods come with guarantees that can't be excluded under Australian consumer law. You are entitled to a replacement or refund for a major failure and compensation for any other reasonably foreseeable loss or damage. You are also entitled to have the goods repaired or replaced if the goods fail to be of acceptable quality and the failure does not amount to a major failure.
-APPLE WEBSITE

here is the site where i got it from.
http://www.apple.com/...-warranty/

so who's right me or the women in the store, should i have been allowed to get a new phone?

Apple Iphone earphones not working?

Ok so I recently just ordered some Iphone earphones from Amazon. The earphones are made by apple company specifically for Apple products.

***Here's a pic if you don't know what i'm talking about: image

Anywho. So I just bought these headphones and they are brand spanking new. I put them into my phone and they work when i play music, the remote works for the volume, and the earphones work when i'm on the phone (as in the hearing part of the headphones work), and the remote works for answering and hanging up. The only thing that doesn't work is the mic. When i'm on the phone, my friend says that he can't hear me but when i put the phone by my mouth he can. Then i tried to move the phone as far away as possible and talk into the mic and when i did he said he couldnt hear me or that i sounded far away. This kinda made me believe that the mic doesn't work. So i just wanna know what's wrong because everything else with these earphones seem to work except the mic and i figure that if the remote works then the mic should too.

Charging Iphone using a Microwave?

I've been scrolling through pages on facebook that post memes, gifs, and screenshots. Anyway, a post that intrigued me was that you can charge your iphone using a household microwave. I'm not a dumbass and I'm doing my research. According to comments, people are saying it works. I even looked on reviews and discussion boards of other websites and people are saying it works. My Question is: Is it true or were they all trolls?
