I’m glad I found this thread! I have replaced more than one cell phone myself and would like to keep an eye out for a more resilient one also.
This may be a little off topic but thought I’d pass this info along.
I noticed the Casio® G'zOne Commando phone meets” Military Standards 810G”.
A few years ago I would have thought that meant a lot more that it does. Then I had to order electronic items like radios and make sure they where compatible with certain working environments. What a learning curve !
Wiki states claims of …"compliance with (any) MIL-STD-810 can be misleading”…
See Wiki’s >>Applicability to consumer products << section at http://en.wikipedia.org/wiki/MIL-STD-810
The 810G water rating is > Rain drip, 15 minutes of exposure to dripping water, Using Method XXX and Procedure XXX. Most commercial products claim “compliance “ with a mil standard but rarely spend the $ and actually have it tested and get a “Certification of Compliance”. Example.. http://en.getac.com/pdf/X500_810G.pdf
One standard I now look for, is if the product has an IP rating , like; IP65.
IP (Ingress Protection) is a two digit code. The first digit describes
the degree of protection against access to hazardous parts and ingress of solid objects. The second digit designates the Ingress Protection against water. 0 is no protection; 6 for digit one and 8 for digit two is the highest protection.
Therefore an IP 65 rating means that the unit is: Protected against access with a wire (1.0 mm), is Dust tight and can handle Jetting water - any direction.
See " IEC definitions" >> http://www.canarysystems.com/nsupport/canary_an4.pdf << for all the levels.
I’m hoping there is already or soon will be an affordable cell phone that advertises a hi IP rating.
