Why can't I delete a TV show off my iPhone 5s?

(Asking in PS cuz lots of people are here) I've tried swiping, holding, EVERYTHING. It's taking up too much space, but when I go to my usage settings, it says videos have NO data. There's no "edit" button that everyone tells me to click on the top right ANYWHERE. How do I delete the tv show?

Which camera should I bring? Studying abroad in London/Travelling Europe?

I have these options: a DSLR Nikon camera, a Sony videocamera (small), or should I buy a digital camera? In addition, i'm bringing my iPhone 5s, which has pretty good quality as well. I'm just afraid I'll lose my DSLR, should I buy a digital camera or take the small videocamera? Suggestions? I will be studying for a semester in London and traveling to a few countries in Europe as well.

Really urgent! IPhone won't charge?

I recently got an IPhone 4 about a week ago and everything was working fine on it until a few days ago I plugged it in to charge and it wouldnt charge i switched outlets and blew in the charger and everything I haven't gotten it wet so I don't think thats a problem but anyways the only way it will charge is when i shut it down completely while its connected to the charger and turn it back on. It won't charge any other way. I don't know what to do about it can anyone please help me?
Also when i unplug it from the charger the battery life is extremely long there's no other prblems with my phone just that it won't charge. But last night when i shut it down and turned it back on to charge it wouldnt charge. So i left the charger and it charged really slowly. It didn't have the charging symblo or anything. I don't know what to do. Could it be the charging cord or is it the actual phone?

Did I blow my iPhone 5 battery by charging it with an iPad charger block?

A few days ago I forgot my phone charger block while on a two day vacation and my friend let me use the bigger block that came with her iPad. It charged my phone just fine for a night until I bought a new block. It charged fine overnight with the new regular block I bought, but now I'm home and it won't charge at all. Like I'll have it sit on the charger and in fifteen minutes it will go from 33% to 34%, then fifteen minutes after that it will go back down to 29%. I don't understand and I think I messed up the battery when I charged it with the bigger iPad charger? It will also just turn off and say I need to charge it when I know the battery is not anywhere near dead and then when I put it on the charger it turns on immediately(unlike taking 5 minutes as if it was ACTUALLY dead) and shows the higher, non-dead percentage. I'm so frustrated by this, please share if you have any insight…

Also, do you think this will be covered by warranty?

Will an apple store give me a new iphone if my battery is bad?

I bought an iphone 5 in March, and since I updated to ios 7, my battery drains super fast. I could leave my phone sitting and it will lose lots of battery. Sometimes I'll be at 40% and my phone will die, and once I plug my charger in, it will say I'm still at 40%. I've heard this could he battery failure or something. If I went to my local apple store, will I be able to get a new one? And Yes, I did purchase apple care warranty.

I need iphone spyware software for someone's phone

I'm looking for some spyware to enable me to be able to track the persons phone and read messages and stuff. Something like this website has to offer ;
http://www.mobistealth.com/package-selection.php?phone_id=542&product_type=ALL

I would of gone for that website listed above but you have to have access to the victims phone and I can't do this. Also, you require to have the victims phone Jailbroken, and again, I can't do this.
Could someone please recommend any Iphone spyware?

Requirements:

- The victims phone is an Iphone 4s ( Any version above 4s is fine )
- I must be able to access the phone WITHOUT having to access the phone and install the software manually ( Meaning I can't get hold of the victims phone as they don't live with me )
- Jailbreaking the victims phone is not optional ( The spyware must be downloaded onto the phone without me having to have access to it )

Any help will be greatly appreciated! Thank you!

P.s - The spyware is for personal reasons only.
