apple iphone 4 faulty spares ?

for sale is a faulty iphone 4. it has a black screen on the front, & the back & home button are orange.. i brought it dead of the internet & brought a new battery and it powers on and goes into iOS but shows a triangle after 30 seconds odd saying temprature to hot to use needs to cool down. The phone also gets very hot when the battery is plugged in and its not turned on. for these reasons it is sold as is. Will update this with a few more pictures later on tonight.
