When I broke the screen on my iPhone, I considered repairing it myself - $25 for the digitizer and my own free labor rather than $99 for Apple to do it.
After watching the "how-to" video on YouTube, I decided that I didn't want to mess with scraping the old glue off the LCD and living with the inevitable bubbles if I tried to put the glue layer on the new one myself... So, I bit the bullet and had the guy at the Apple Store do it.
Amazing. He was done in FOUR MINUTES! So yeah, that's about $1500/hr but it was well worth it to get it done right and done fast.
Just curious, what are they charging for the repair?
