It seems like this would have been addressed at length here, but search isn't yielding much results. i recently bought the Groupon lifeproof nuud for iPad mini with the impression that it worked with the retina display version too (groupon indicated as much) today i get a notice that it supposedly doesn't work with the retina version. i understand the issue with the two mics and don't care about that. what i care about is waterproofing. the retina version is .3 mm deeper, will that depth render the waterproofing useless? nothing looked out of the ordinary when i put it on and if it weren't for the email today i wouldn't have given it a second thought.
