I don't recall this being listed as a feature but the SR floats!!! How do I know? Well, about mid stream, yes browsing the internet and relieving myself, the slippery fish that is the SR, jumped out of my hand and directly into the toilet...in slow motion no less. As it torpedoed the surface of the yellow sea, it quickly gained control of the situation and became boyant floating toward the surface, as if doing the back stroke. In horror, not thinking twice about plumging my hand into the bowl (it was my bowl after all and only a number 1), I grabbed my i727 and quickly ushered the device to a towel on the countertop. I quickly removed the battery cover and began inspecting for water intrusion. Compressed air can helped remove moister from the edge of the phone, mini USB and head phone Jack. Long story short, the SR is one air tight device. I'm not sure if Samsung was hedging for potential submersion but it sure looks like it. No damage that I can tell and its been 24 hours since the swim. Speakers and buttons all operable. I've learned a lesson...no urinating and web browsing with a slippery phone...I just need my pop case to show up and I can multi task with a good grip!
