Does Opening the iPhone Violate the Warranty?

Yes you will void your warranty by opening up your phone. At this point it doesn't matter since your warranty doesn't cover water damages unless you purchased some insurance that does. You do need to disassemble your phone and deal with this. The gist of the procedures to disassemble are here. Clean your printed circuit boards with rubbing alcohol and and a brush. Then submerge and agitate (move them around) them in alcohol to ensure that the ICs (Integrated Circuits)with BGAs (Ball Grid Arrays) have been flushed of contaminates. Wipe them with paper towels, changing them often, to ensure you are not smearing residues or contaminates to other places. Use a hair dryer ( on low to no heat) or a fan to expedite the drying process. With the use of the fore mentioned continue to let them sit over night to dry. Let them sit at least 24 hours with out the aide of air flow. Reassemble and give it a try. Good luck and have a wonderful day!

If your iPhone has gotten wet on the inside, the Liquid Contact Indicators (LCls) located in the phone will be activated by turning red. The location of the LCI differs with each model. Details at http://www.etradesupply.com/blog/rescue-...

At least you can read this guide to know how to retrieve files from a water damaged iPhone.

Actually, all of these answers are completely correct... if you don't know what you're doing, have proper tools, and have confident comfort level... have someone who does take care of this as in re/moving some things you can actually damage cables etc on phone that causes a bigger problem.

I'm a little late and it's probably not particularly relevant, but if you're in the US, the 1975 Magnuson-Moss Warranty Act apparently makes it illegal for them to void your warranty just for opening your phone (or any other gadget) and performing simple operations like removing the battery. http://motherboard.vice.com/read/warrant... gives a nicely readable explanation.

Of course, even though you can recover your legal fees and court costs if you win, it's much less bother just to buy a new phone, so it's fairly irrelevant in practice. Still, nice to know.

You shouldn't open it up it could also void the license agreement .

But here are some tips:

1. Put your phone in a bag of rice make sure it is completely covered and keep there for the rest of the day

2. If the water damage prevents the phone from turning schedule an appointment with the Genius Bar

3. If you can Backup your data and get a iPhone 7+ and restore from iCloud.
