I have an opportunity to purchase an iPhone 4 8gig for about $50, but it has a broken screen. I have been thinking about switching from my Galaxy Nexus to an iPhone and thought this might not be a bad way. How much would a new screen run me? Keep in mind I don't want to dump a ton of money into a phone I may not like. I have no idea how much it would cost to fix. No one in my area fixes them and I don't like the idea of sending it to someone I don't know. Any help would be appreciated.
