Can you repair and iPhone screen if it is just a little cracked, or do you have to replace it?
yes you can... just go on ebay and look for front housing replacement but the only thing is you need someone to install it for you or learn how to by watching utube videos on how to replace front housing screen
There is no way you can repair the screen of an iPhone if it has a crack no matter how small it is. The only option is to replace it with a new one.
Must have it completely fixed?
they can get u a new screen thats wat they did to my uncle
depends on which iphone it is if its a 4 im pretty sure they have to replace the whole phone but if its older like 3gs you can replace the screen but insurance will NOT cover it.
