Not particularly difficult. I watched a tear down video on Youtube, then bought the replacement screen online. There was a gasket of sorts between the screen and the chassis of the phone which had to be destroyed to remove the screen. I used thin tape as a substitute. Going slow (never having done this), it took me less than an hour. The screen was a little over $100. At the time, I was still under a 2 year contract, so that was cheaper than getting a new phone.
