But this time may be quite short - 20 seconds or less. So grab your phone quickly! If not, you can turn it on underwater, try a few numbers, and talk to your friends. They can't understand you, but it's fun. Just remember to come up for air.(Just Joking!)
2. Remove the battery. This is one of the most important steps. Don't take time to think about it; electricity and water do not mix. Cutting power to your phone is a crucial first step in saving it. Many circuits inside the phone will survive immersion in water provided they are not attached to a power source when wet.
3. Remove your SIM card. Some or all of your valuable contacts (along with other data) could be stored on your SIM. To some people this could be more worth saving than the phone itself. SIM cards survive water damage well, but some of the following steps are unnecessary i.e. don't heat it. Just pat it dry and leave it aside until you need to connect your phone to your cellular network. Note that many phones by specific providers, such as Verizon, do not use SIM cards.
4. Dry your phone. Obviously you need to remove as much of the water as soon as possible, so you can prevent it from getting into the phone. Use a towel or paper towel to remove as much of the water as possible.
<snip>An alternate drying technique is to seal the phone (battery, SIM card, SD card all removed) in a plastic bag with a few of the silica packs that come packed with shoes, coats, electronics. Leave the phone in the bag for a day or 2, and the silica packs will absorb the moisture.
The silica method works! Go to local craft store and purchase flower drying kit. Silica contained in this kit is like sand, spread on bottom of tupperware container and place a piece of tissue paper on top to lay your cell phone on without laying in the silica sand. Seal up tupperware and let sit for three days.
The new crystal cat litter works as well as silica, and if you put all phone parts inside a sock or knee high pantyhose and bury it in a new, clean container, it will dry out in just a day or so.
