I have dropped several in the lake. Very interesting on the dry ice. Never heard that before. Be interested to see if it continues to work trouble free over the next few weeks. I have always been able to bring mine back to working order with an air compresser blow out and either a hair dryer or sitting the dash for an hour with the defroster on high heat. The only problem is everyone has developed a quirk a couple weeks later. My current one rings sometimes and sometimes not.
WOW...I completely missed the "r" too. I read it as 'dry ice". As a matter of fact, I just told my wife about the "dry ice" trick and she looked at me funny. Now I know why as I read it completely wrong. I guess if you really think about it...if you put dry ice on a wet phone, I imagine the water in the phone would freeze solid but hey, I thought if someone posts it here, I believe it!
You can also bake them over night in a 150-175 degree oven too. Make sure you have it under control or you'll end up with a puddle of plastic or worse. Most of the plastics and components of a cell phone should take temps higher than that. Exercise this tip at your own risk.
