What is the difference between all the lcd/digitizer assembly's
I'm looking to buy a new LCD/digitizer assembly for my iphone 4. I was looking on eBay and the prices vary from $25 to $ 120. I know I need to buy the whole assembly ( LCD and digitizer) together. I'm just wondering which to get and what the differences are and how do i know what I'm getting (other than making sure I'm buying from reputable seller. Thanks.
Is this a good question?
