If you decide to go Android, I bought a Samsung Exhibit 4g for about $199, unlocked, from Amazon. I then bought a TMobile prepaid, no-contract card to pop in the phone. I pay $75/month for unlimited talk/text/data at 4g for the first 5 gigs (after 5 gigs of data it gradually throttles back the speed from 4g down to 3g -- but 5g is a TON of data). Amazingly good deal. Nice, rugged, better-than-average phone. And I love Endomondo app for biking and kayaking and backpacking. I also use Backcountry Navigator app (it costs $5 or something small). You can upload GPS routes to it and also use it in airplane mode so it is very gentle on the battery.
