If I buy the parts will you replace my iPhone screen for free, I've a ton of facebook friends I'll make a post saying how good you are.
How about no. Even if I did do it ant it worked out well I just know that in 2 years time when they forget their passcode it'll be my fault because 'you we're the last person working on it'
But, I'm lucky in the sense that it was never more than a sideline so it was pretty easy once I got jaded to pack it in.
