No Service on my iPhone 4s on Tmobile?

For the past few days my iPhone 4s has had trouble connecting at all to tmobile, ee, 3g or even Wi-Fi. It is only in certain places that it does not connect at all (one place is my house) but anywhere else I have really poor connection. Any idea why this could be and how I could fix it?

I have had this phone for nearly a year and I have never had problems before.

How to switch iphones on verizon?

How to download music to and iphone from an unknown band?

I love the band "the vamps" they do covers on YouTube but I would like to have some of their covers on my iphone and iPad. I have looked on iTunes to see if you can buy them but you can't so I was wondering if there's a way to download the music from the Internet?

Do I need a receipt to take out insurance on my Iphone?

I have an Iphone 4; I inherited it over a year ago from my Dad who upgraded his phone to the newer version and got to keep the old phone. So he gave it to me. I want to take out insurance on it now as I'm going abroad for a few weeks and I'll be staying in a tent, so I will not have a secure place to keep it. I also think it's a good idea to have insurance in general as I won't be able to afford to replace this phone if it breaks and I really like it.
But because I inherited it, I don't have anything like receipts or anything to say I own it or when it was bought. Does this mean I can't take out insurance for it? I've obviously seen that I can take out insurance for it, but can I make a claim if I had to without anything?

Photographers, what is this?

My iPhone has adjusted to focus on details in the clouds via my excessive use of camera to snap pics of them. This has not influenced any other eventual pictures taken by mí phone.

So of course this is normal right. But photographers, what term would describe this happening?

Where to get a used or refurbished iPhone 5 16gb for cheap?

I have a iPhone 4 16gb and I'm with AT&T. They have a special if you trade in your old phone, you can get the iPhone 5 16gb for $99.99 but after taxes and a $36.00 renew your contract (the $36.00 can goes on your next bill) if you add in the $36.00 my total will be $143.98 ($107.99 if you don't count the $36.00 that will go on your next phone bill). I wanted to buy an iPhone 5 for about $107-$125ish, but every time I go on eBay or amazon, everyone wants $300-$600. (and its like dude, the iPhone 5s is about to come out, lower the price). I really want to buy an iPhone 5 but not from AT&T, I can get more money by selling my iphone 4 than trading it into AT&T. What do you think I should do? Where can I get an iPhone 5 for $107-$125? What legit websites beside eBay and amazon can I get a used or refurbished iPhone 5 16gb? Any help or tips are welcomed, thanks
