So not cool... I drowned my MT3G slide today!
Fell right in the sink. Got a MyTouch 4G Slide to replace it, which seems like a pretty sweet device so far. Just need to keep it out of the sink!
It's probably too late to try now, but you never know and for future reference, I thought I'd share this for those that do not already know....
The sooner you do this, the better your chances for saving your phone!
If your phone gets wet:
PULL THE BATTERY! As quickly as possible!
Dry phone as best you can, without shaking, turning over too much.
Remove SIM and SD Card. (Pat then air dry)
Use a vacuum cleaner and set up everything where it can pull air through the phone, preferably where the water entered. (It could take a while, but at least 20-30 min on each section of the phone where water could have entered)
Never use a hair dryer due to moisture + heat can damage components and compromise adhesives. Also, I have heard that it is best to use a vacuum to suck air through, rather than something to blow air in so you do not push moisture deeper into the phone.
Bury your phone in a bowl of dry rice overnight. (Silica packets that come packaged with electronics and other products can work even better than rice, but only if they have not already absorbed their max amount of moisture, which I have read that many have.)
Carefully inspect phone for any leftover moisture. It may help to use vacuum again both for moisture and any rice dust.
When trying to power on phone for first time, leave SIM and SD card out. If phone does not power on, try removing battery and plug into charger. If it comes on plugged in with no battery, the battery is likely bad.
I have also heard of people flushing their phone with cleaning alcohol to displace the water and let the alcohol evaporate, but I have also heard that this is a bad idea. So I would play it safe and NOT try this method.
Another tip, and a somewhat surprising one: If your phone gets SALT water inside, after removing the battery, SIM and SD card, flush the phone with FRESH water! This sounds like it would be a very bad idea, however, when salt water evaporates, it leaves corrosive crystals behind which can cause even more damage to the internal components. Flushing it with fresh clean water may reduce the chances of this happening.
There is NO GUARANTEE that any of this will work for your drowned phone, but then, if it comes to this, what do you have left to lose? I have been fortunate enough to not have had to use any of these tips, so I cannot speak from personal experience that any of them will work any better than just letting it air dry for a couple of days. Some methods are also risky and could potentially do more harm than good, so it is entirely up to you if you even want to try them.
I just think it is better to try something than nothing, and hopefully this will save someone the trouble and cost of being forced to buy a new phone.
