How much does it cost to get the back glass of an iPhone 4 fixed?

I recently cracked the back glass of my iPhone 4. I don't have a warranty and my school have it to me.

If you put sand in the cracks then boil the kettle and pour it on the phone the sand will melt into the glass and itll become new again its what apple do. Hope this helped

$100.00 to $120.00 not including labor

You can buy a replacement Apple iPhone 4 back from Amazon for about £10, and its easy to fit! All you need is a small head screwdriver to remove the two screws next to the speaker on the bottom of the iPhone, then the back slides off, and you just put the new one and a put the screws back in, simples! Overall cost £15 (Would need to buy the correct screwdriver)
