Can I take my iphone scuba diving?

I have an iPhone 5c, and it's in a lifeproof case. I've been swimming with it, in the pool and in the ocean, and even cliff dived with it and there weren't any problems. I'm going to be scuba diving, which will be about 35 ft deep underwater, will it be ok to bring my iphone down for pictures? Will the depth be a problem?

Of course you can, but it might get destroyed and useless if you do.

Is the case rated to depth?

certainly just because case has functioned fine as youve used it so far does not guarantee it will function under the greater pressure you are proposing
