Already cracked my 6s screen, are they avaliable for replacement yet?

you should be able to have it replace, or if it's under warranty, you could get an entirely new phone. also, I think that some screen repair stores may be able to replace your screen. I suggest you do some research before you settle on just one place without knowing others prices. hope you can get it fixed!

Get it fixed by Apple, do not let anyone else work on it, or the warranty will be invalid and Apple will never work on it.
