Dropped phone in water, screen is black but sound still works

Depends how wet you got your phone the less amount of water it was submerged in the less amount of days. If you had dropped it into a body of water and was in for 1 min or so I would let it dry in rice for the most of 2 days the longer submerged the longer you sit to dry. But if it still doesn't work after a week or more of drying then time for a new phone.

You can try it back in the rice for another couple of days more, but I think most likely damage has occurred and you'll need to pay for repair or a replacement.

Regards.

Leave it in the rice for 2-3 more days before turning it on again. Tuning it on while still wet is may damage it more than leaving it off to dry slowly.

You can try to dry it out more, however, I think it is shorted out.

BTW, if you recently bought the phone new from AT&T the $200 price you paid is probably the subsidized price. The unsubsidized price for a replacement iPhone is much, much higher. You can try to get your carrier to sell you an iPhone at the subsidized price. I don't know of any program that will allow you to buy another one at $200 before the term of your current contract expires. Maybe your carrier will give you a break though. Good luck.

My phone has th3e same problem at the moment, my screen is black.. It is currently sitting in rice, how long should I leave it for? When is it safe to charge my phone again?
