This is confusing. When I see the words '2g original iPhone' I think of the first one that ran on AT&T's 2g network (edge) with the silver back. Is that what you're talking about? If so I really doubt people are finding replacement parts for 40 bucks. The glass and LCD is fused on that model, like on the iPhone 4, and are pretty expensive. Also the glass is a major pita to replace. If you can find someone to swap out the glass on one of those for $120 I say do it and send the boy an invoice. I charge over $200 for that repair and absolutely hate doing it.
