Where can I order the iPhone 5S Sim Free 16GB Gold?

I have no intention of buying it now, or in the next month… I just want to know the place to buy an iPhone 5S, Sim Free, online for the 16GB Model.
I've searched Amazon and in the Apple shop it only shows me contract versions, and I want a SIM Free version.
Now, I'm looking for the 16GB version too.

IPhone 4 screen is going crazy! What's wrong with it?

Okay, so a few months ago, the very right side of my screen stopped working. So when I typed on the keyboard, it wouldn't let me press the 'P' button or the '0' etc. But all I had to do was flip the screen around and it worked, so that didn't bother me.

But last night, I was typing a message on my phone and it started pressing different buttons and then sent to the person I was texting. I thought it was just a one time thing, so I cleaned my screen and went to type again. This time it went to the home screen, onto the iPod and started playing my music and flicking through to different songs.

I've noticed that it only presses certain buttons (Certain parts of the touch screen) its the whole of the right side still, a spot in the centre and a couple of other spots on the screen.

It's definitely not from anything on the screen as I have cleaned it multiple times, and it's not from my fingers either as I have put it down on a flat surface not touching it and it still does so.

I can't really use it now because every time I open up an app, it messes with it and the settings and keeps sending messages to people. Does anyone know why this is happening and how I can get it fixed? Or how I can use it temporarily without any problems as I'm due for a new phone next month anyway.

Trying to restore jailbroken iPhone 4, getting Itunes error 3194 and error 11

I want to wipe my jailbroken iphone 4, on ios 5, so i can update to ios 7. I used tiny umbrella and managed to get past the 3194 error, but then I'm getting error 11. I have tried to erase and reset through the phone only, but it simply shows an endless loading ticker, and not the apple logo and loading bar. How can I reset my phone?
Thank you for anyone who can help!

Downloading music from chromebook to iphone?

I recently purchased the asus chromebook c7. I already know i can't download iTunes to the chromebook, but is there anyway I can get music downloads from, say listentoyoutube.com, to my phone?
