I would take a serious look at the Kyocera Hydro line of phones. I have the Hydro Icon (Sprint T-Mobile), and the Hydro Vibe is the most popular one available via Verizon/AT&T. They do everything you are looking for (basic smart phone), they run android (which as a PC User, I feel is superior to the Apple line, unless you just REALLY do not know what you are doing), and they are more durable and water resistant than the Samsung line of phones.
I work in plumbing/Electrical trade, and I constantly am submerged underwater and my phone falls into pools of it often. They take a licking and keep on ticking. And they are INEXPENSIVE.
I bought my Hydro Icon, no special promotions of any kind, for about $150 out the door. I got a very basic shock absorption case, and I check my e-mail every morning (and this website) from the shower. With the shower on. I've been doing this daily since July. I've dropped it into the water at least 3 times.
Some of the Samsungs that advertize similar results are not anywhere near as reliable. I've seen even the Otterboxes fail on such phones.
iPhone 5 is a nice product. But if you haven't already, play around with android. It is a bit more customizable, and it tends to innovate more quickly. The Kyocera phones are sleepers. They will take some serious market share soon.
