from the research i did, cause my wife's is cracked, when you replace the screen you also have to replace the touch part of it under. like it's not just the glass. and the cheapest i saw those parts was like around $130 or so.
my brother got his ip4 screen replaced for like $100 from someone local so i'm not sure if the ip5 would cost more, but i'd probably just pay someone to fix it for me who knows what they are doing
