Matching up to the IP67 durability spec means it's expected to resist being submersed in up to a meter of water for up to half an hour...
Many other blogs and tech sites twisted the words from Engadget into claims that the Defy is definitely IP67 certified. Similar claims are all over thos forum too.
But is it really IP67 rated?
Motorola never claimed that the Defy is IP67 certified. They carefully avoid the word "waterproof" and their documentation clearly says that the Defy is not meant to go swimming. Their recommended drying procedure in case your phone gets wet doesn't sound very reassuring either.
Once you've unlocked and relocked the microUSB cover a hundred times or so it's hard to believe that it still keeps water out. The battery door latch also gets looser over time.
Pictures and videos of phones in pools and glasses of water don't proof that the Defy has an IP67 cert. They only show that the phone resists water under the conditions used in the picture/video, which are not the same as real world conditions for a phone that's been used for a few months.
Just because the IP67 story is copied all over the web doesn't make it true, so until someone can link to hard evidence I suggest that we treat the IP67 certification as a rumor, not as fact. Of course the hard evidence should come from Motorola itself. Tech blogs don't count.
