Have accidentally deleted everything from my Iphone 5?

I have a brand new iphone 5, just delivered to me - insurance company paid out for my old one as it had got water damaged.

I have spent ages restoring the new one so that it has everything on it that i had on my previous iphone and it was working wonderfully…

I logged onto the find my iphone app and can still see my iphone (offline) however, this was going to be destroyed by my insurance company, so i decided to erase the phone so that no details of mine would be on there as i have banking details everything you can think off on it.

I selected the erase your iphone - button pressed - seemed fine

THEN…

My current iphone, went black the apple sign came up and now it wnt turn on - its deleted my new iphone!

Its deleted everything as the phone won't even turn on now - how in gods name do i rectify this as i can't claim on the insurance again as i hadn't even given them any new details!

How to make iphone app games from scratch? Recommended books etc?

I have decided I want to pursue a potential career in making games. I have very little knowledge in how to do so, and would love some tips on where to start. I'm prepared to spend a hell of a lot of time learning if necessary, as I have a few ideas for games, and would love to make them even if its only me playing them! Any courses/books/tips?

I just don't get this whole calories and kilo calories thing?

I want to loose 15 kg (33 lbs) in 2 months. I'm currently 95 kg(209 lbs) and I'm 180 cm tall (5'10").
I know that in order to loose 1kg I need to burn 7709 calories. ( 3500 calories for a pound). Today I worked out and lost about 560 calories accroding to my running tracker app for iPhone. Now I ate a dish of pasta with sauce. I read on the label of the pasta plastic bag that for 100g it contains 350kcal. The whole thing is 400g and I ate about 200g of pasta which means that I've consumed about 750kcal which according to Google is 750.000 calories.So, some basic math (700.000 / 7709 = 97.2), and I've put on 97.2 kg? I just don't get it?
Please clear my mind.

Why won't my music work on my iPhone 4S?

Whenever I play my music it takes away the volume so I can't turn it up or hear it. I've tried putting the hair dryer on it but that hasn't made any difference.
Anyway I could fix this?
