It will never be the same again but put it completely inside a bag of rice or cous cous and leave it there for 2-3 days. You may be able to use it but functions like the camera may not work and the screen will have liquid marks on it.
This is what happened to DD's iPhone which fell into into a glass of water beside her bed. It's useable but the camera is knackered and the screen looks odd.
I dropped mine down the toilet when I was in hospital. It was fine at first then got really hot and died. I was gutted, obvs.
DP took it with him and put it on the dashboard of his car so the glare from the sun could bake it so to speak. I think he got this tip from the internet. A few days later he turned it on and it was fine. No damage what so ever! Still working fine 4 years later.
It's absolutely dead unfortunately but when I had a panic that I'd lost all the pics of my baby trusty dp reminded me he set it up so that everything goes to my iPad and iCloud I don't know how to use iCloud
