Would the iPhone screen crack in a black hole?

No.
It would crack before entering the black hole, which is a point source. Given its size, shape, and composition, and assuming we can discount thermal deltas, it's likely that gravitational forces would shatter it at approximately (pulls out paper, does some math) 1.68 times the radius of the event horizon of the black hole in question.

Well it can't just magically disappear...
The gravitational force from the black hole would crush it before it enters. Whether it cracks the screen or just crushes it is unknown.
Last I heard, Hawking had all but proven that information is not destroyed after impacting the surface of a black hole. So the phone should be good for thousands of billions of years. If his theory includes the eventual evaporation of a black hole via Hawking Radiation (it may have but I'm not sure), then the phone could theoretically last as long as the universe itself, including the screen. Quite a bargain!
Oh...and yeah, the screen would likely crack long before crossing the event horizon.

ya dude i was watchin the live feed of it http://www.cyriak.co.uk/lhc/lhc-webcams.html
and that ***** kinda kool im gonna store my iphone in a black hole and hop into my own lil black hole i got by me and then live happily ever after with my iphone i wonder if there is wifi in black holes
Lets see if i can add to this:
If you threw your iPhone into a black hole, you wouldn't see it break. It would freeze in motion as it falls towards the black hole from the time dilation effects.
On the other hand, the extreme gravity will cause it to spaghettify (near-technical term) and the phone/screen will shatter.

No, but some lucky person in an alternate universe would get a free iPhone
3g coverage is bad enough on earth, so theirs will be useless.
I'll ask my brother, who's working on an applied physics masters from CalTech - I mean, he once debated the effects of a werewolf living on the moon with his professor
the iPhone will "spagettify" (is that right?) before it even enters the black hole so im pretty sure the glass would crack. although the plastic and aluminium will probably which are more malleable will probably keep intact for a little while longer.

Just a quick fyi, yes, you are the only one concerned about this.
This is pretty much spot on, though the spagettification (you are correct) would be less than that of, say, a human due to the shortened length of the iPhone in comparison. Glass is nothing more than a slow-moving liquid, so under several thousand gravities, the screen might just "moosh" together like the rest of the components as the iPhone is slowly torn apart, molecule by molecule.
LOL. not sure about black holes but my friends iphone the other day survived a drop. he dropped it from his hardwood staircase from top to bottom. he's a rich spoiled kid (but not "snotty") and he was hella scared. he doesn't protect his stuff with cases. but when he got it back, no scratches. screen was perfect. the back was fine. mind you, this isnt some carpeted stair, it was hardwood and its one of those spiral stairs. the really wide ones.
yeh i reckon if the iPhone was a few light years away from the black hole it would probably be just a massive line/collection of aluminium, silicon, carbon, oxygen and hydrogen etc. atoms. by the time it gets there.
It depends on the alternative universe. One of the theories I've heard is that there is an infinite number of alternative universes, one of which is just like this one except that you're not there. Another is just like this except that I'm not there. So there has to be one where AT&T doesn't suck, 3G actually works and the monthly fee is reasonable.
