Took about 15 minutes. The only thing that was confusing was the reference to parts, using the partname, and I didn't know what they were referring to. So I had to figure it out by the photos. Slightly frustrating. Got it in and it worked. My problem then, was it kept SEARCHING and couldn't find my carrier. I followed everyones advice on here, plugged phone into my computer to itunes. then turned off network settings in settings, then turned them back on, and I got 3 bars. good to go.
