Do they transfer everything from an old iPhone to a new one at the store?

This Thursday I'm going to get an upgrade. I have an iPhone 4 and I'm not sure which one I'll be upgrading to yet. But I was wondering if they transfer everything from your old iPhone to your new one (pictures, contacts, texts, apps.) It's really important that I get all my contacts into my new phone imediately, and although photos are important to, they're not absolutely mandatory. Before I go to the store I'll probabky transfer my photos onto my computer just in case.

IPhone 5 (Vodafone) constantly losing service?

How to download voice recording to computer?

Need advice from iPhone users?

I currently have the iPhone 5 but I smashed the screen, however I'm due a free upgrade to the iPhone 5c. I don't like any of the brightly coloured ones so I would choose the white one, but I'm worried it will look cheap and "plasticy".

Alternatively, to upgrade to something else I can pay:
£100 for a 16GB iPhone 5s
£200 for a 32GB iPhone 5s
£200 for a 16GB iPhone 6

I guess what I'm really asking is whether I should pay £200 for more storage on the 5s, or the same amount for less storage on the 6 (I will be using it mainly for Spotify, social media, taking photos etc, however I do not STORE many photos on my phone, I will move them to iPhoto on my Mac).

I'm looking for anyone who has owned one or more of these phones (5c, 5s, 6), how do they compare? Which would you choose out of the options above?

Using my iPhone in Scotland?

I'm from the US and I'm visiting family over in Scotkand for about 2 weeks. I've heard that using your smartphone internationally is very expensive. Would it cost a lot to text or call friends back home? Does getting Wi-Fi there make it any better? I plan on texting with iMessage, posting on Instagram and sending Snapchats to friends back home in the US. Would that cost a lot to do? I'm not really familiar with using my iPhone internationally. Can someone please explain how this all works and answer my questions?

IPhone Wi-Fi forgetting network?

How do I stop my iPhone 6 plus from connecting automatically (when Wi-Fi is enabled) to a particular network? My gateway has both 2.4ghz and 5ghz and I don't want it connecting to the 2.4 one because it's very slow. I have Comcast by the way. Whenever I forget network it forgets the 5ghz one too.

How to turn off the monitoring on an iPhone?

I heard that apple monitors everything on your phone. I also heard you can turn it off in settings. How exactly do you do that in detail?
I want to download music but I obviously don't want monitored and potentially sued for downloading music. I can't find an app that will allow me to download so it takes data to play my music as it's slow.
I used to have an android and downloaded music free no problem on an app. Makes me miss my galaxy…
