Instead of spending $200 on paying someone else to do it, you can spend about $30 and watch these YouTube videos below and fix it yourself!
You will need a Replacement Digitizer and Touch Screen LCD Assembly Kit (be sure to choose the color that matches your iPhone and the correct iPhone model as you will be replacing the entire face plate).
This iPhone screen replacement kit comes with all the tools you need to be able to take apart your phone and put it back together: tiny screwdriver, pry tool, suction cup, etc, and the touch screen itself, of course.

That’s it! You can save yourself a couple of hundred bucks if you have the patience to undo all those tiny little screws. It is important to remember that this DIY fix may void your manufacturer’s warranty, but if you’re only a few months short of a free upgrade I would say it’s definitely worth that risk!
