Which color and Configuration of the iPhone 6 should i get?

I'm upgrading from a 32 GB iPhone 5 and I noticed that i have a lot of extra storage left on the phone so would you guys recommended the 16 GB? And Any Suggestions on the color? I'm leaning towards gold But the antenna bands are so noticeable and the gold kinda looks a little "dull" or "pale"? I'm not sure if this was how it looked from photos or not, thank you id appreciate any answer!

Added (1). One last thing, i noticed that the iPhone 6 has a protruding camera lens, I've heard some rumors that there's a layer of of sapphire crystal to Protect the lens from being damaged, i just wanted to know if this was true, Thanks again.

What's wrong with the App Store on my iPhone 5C?

I have an iPhone 5C with iOS8, and earlier today I opened the App Store to search for an app. At the bottom right corner of the screen (where it says 'Update'), there was a number 1 telling me there was 1 app that needs updating. But when I went to the update section of the App Store, all the apps were up to date.

I closed the App Store (by double-clicking the home button and sliding the App Store up to close it fully), and then reopened it, but I'm still having the same problem. Does anyone know what the problem is and how to fix it please?

IPhone 4s only charges when plugged in and turned off?

I recently found that my IPhone 4s only charges when the phone is off when plugged in. But the phone shows no sign that it is charging, no red battery when its turned off, i just turn the phone on and its charged to 100%. I've had the phone for longer then a year, so i took it back to the company which sold me the device and they told me they had not seen or heard anything like this, They told me to take it down to my local apple store. But after booking an appointment apple told that they haven't heard of this before either and they think it could be internal apps crashing or the software, they done a test on the battery and they said the battery is fully healthy and the dock is not dirty or broken. They also said the problem is not the fault of mine. But because i have going over the years warranty apple have said it will cost £126 to be sent to be repaired and the company which i bought off have told me it will cost £146 to be replaced which i can't really afford at this moment. I can't connect the iPhone to the computer or anything. If any body has any idea of what this is or what i can do to fix it will be much appreciated.

Front iPhone 5S camera grainy?

Okay so the front of my 5S is really grainy when I take pictures and you can hardly see. I've noticed that inside that the glass covering the lens is shattered. Is there anyway that I can get that fixed with out getting a new iPhone? And my phone is jailbroken so the warranty is voided.

Is there a noticeable difference between the iPhone 5 and the 5S?

First of all sorry for my English.

I'm about to replace my iPhone 4S, and I want to know if there's a significant difference in terms of speed and smoothness between the 5 and the 5S.
I don't really care about Touch ID, I just use my phone for facebook, whatsapp, snapchat, instagram and google maps.
