How much would I have to pay for an iPhone 5 if I exchanged my 4 in?

Are there any reputable phone shops which will allow this? My phone was bought for a Christmas present (presumably from the apple store) and is in mint condition with boxing and earphones etc.I'm wanting to upgrade to a 5 because unfortunately the 8gb on my phone is just not enough, and the camera on the 5 is much better. I would be prepared to spend about £170-ish to upgrade as well exchange my 4 in. If anyone knows how much this would actually cost and if there are any places which do this your help would be greatly appreciated.

Should I get the HTC One or wait until the next iPhone is released?

I have the Galaxy S4 but its not working so I have to get another phone. I should wait for the next iPhone and then decide between the two, right?

Added (1). I wouldn't be without a phone because I have a BlackBerry so I'm using that. There's some problem in its software, so I don't want to spend money on getting it fixed. Its not on warranty. I can wait for the iPhone. Should I wait? I'll be getting my new phone in October anyway. So I'll have to wait for it either way.

Will 300MB be enough each month for an iPhone 5?

So I'm not exactly 100% sure what the 300MB do. But it is the cheapest plan for Verizon, and I was wondering how quickly it would be used up each month? All I would really do with the phone is mainly twitter and Instagram, text and call people only when I need to, and take pictures and videos. And of course a few other apps, but I don't think that has to do with the amount of MB. Will 300MB last me each month if I use the phone for only these things?

Can you put IPhone 4S internals into an IPhone 4?

I know the display and digitizer will work on both. What I would like to do is completely gut my Iphone 4S, and place all of the internals in my IPhone 4 body(because the display, frame and back cover are all in mint shape). Can this be done? Do the screw holes line up?

How to connect iPhone to MacBook Wi-Fi?

I need to know how I can use the Wi-Fi system my computer is connected to, to act as a personal hotspot for my iPhone. I use a USB internet router in my computer so I can have access to internet anywhere but I would like to know how I can hook my phone up into this as a hotspot because I don't have any cellular data on my phone.

Iphone can track you via GPS on pics u post?

I was reading that the smartphone has tracking in the pics that will divulge your location.

So these people posting with i phones are just giving out their locations to the world.

One more reason i don't need a smart phone.

Added (1). I'm not talking about making and receiving calls. The pics you take with the smartphone will tell your location.
Example: you are hiding from your ex- g/f and you owe child support and she can track you right to your house.
Example: You are metal detecting your favorite site for coins. Or your favorite fishing hole.
or your kid puts her pics on facebook and every pervert knows her address.
