I've lurked around here for quite a while now, but finally decided to take the 30 seconds to register...
I don't care about the original price of the phone or anything, but $199 to replace my cracked screen on my 3G and the retina display costs $28?![]()
It's $199 *installed*.
You can buy a timing belt for about $30, but it will cost over $300 to have it installed by a mechanic. Parts are different from - and usually cheaper than - labor. There's nothing even new about this.
