IPhone won't connect to mac?

I don't know whether I need a new cable or not, but If I plug my phone into the wall it's completely fine.
I got a new computer which is a mac, and i've just done all my iTunes etc so I want to update my 5C

I've tried unplugging, flipping over the cable etc. But nothing is reading at all, nothing saying it's failed. Just acting like it's not there at all.

I have a feeling this may be something simple to do, and I just can't seem to figure it out.

Any Ideas?

Best windows laptop for under 400?

I want to convert a friend to Windows, and I've showed him the Surface Pro 3 and my three Windows devices. He has an iPad air and an iPhone, but not a laptop. When I went round to his today, I had a game on my laptop that we couldn't play because it was not available on Mac.

If he was going to get a new laptop, what Windows laptop would be best within this range?

Added (1). £400

My iphone was stolen. Please?

My phone was stolen and when I went to track it on Find my iPhone it was already offline. I put it on lock mode. But what happens if the thief resets it to factory settings? Do I get a notification when he/she connects to the Wi-Fi or am I not gonna get anything if they wipe all my data?
Thank you so much in advance!

Added (1). Also if I report stolen to AT&T would I still be able to use Found My iPhone with it?

Why isn't my iPhone 4 turning on or charging?

Nothing has happened to it. It randomly shut off when I wasn't looking and when I picked it up it wouldn't turn on or charge. I Can't try and reboot it with the home and lock buttons because my lock button is broken. How can I fix this, it won't even connect to the computer

Should I get the Sony Xperia z2 or wait for the z3?

Ok I have an iphone 5 right now and before I had the nexus 4 but I sold it due to screen problems(dead pixels) so dad gave me his iphone 5 after getting the 5s. IPhones are cool in ways but I think I prefer android phones overall (the good android phones) I like nexus so I was thinking between the nexus 5 and z2 and I've kinda decided in getting the z2 the nexus 5 is great and it's a nexus but the z2 just offers more for me. Anyways mum said she might get me a phone after we come back from holidays (August) and when I sell my phone. So possibly August. So sony releases phones every 6 months and the z2 was released in April I think which means the z3 will be released in October. Ok so the good things about getting the z2 is that it's going to be cheaper and I'm getting it before the z3. But the z3 is probably going to be better but more expensive and I'm gonna have to wait longer. Mum also said it depends on the budget so I'm taking the price into consideration. So what do you think?

Got an iphong 3g but don't know what to do with it now?

My uncle found an iphone 3g a few months ago he gave it to my little sister and she traded with my big sister for 2 coolpads (bigger phones). Soon my big sister traded the iphone for one of my jackets that she likes. Now my little sister is mad because the two coolpads broke and my mom threw them away she wants the iphone back now. While i was gone she took the iphone and the charger and she put a passcode on iphone, but now the charger is broken and the iphone well i don't know the passcode too it and she will not tell me the passcode unless i let her have the iphone back i'm not going to do that because she is too reckless with phones she does not care about her phone and when it breaks she expects our parents to buy her a new one.it has the sim card and stuff and it's almost dead i don't want to give it back to her because i don't think she deserves it what should i do.
