+1. We have an iPad, Windows PCs, and Android phones. Navigating any of these is easy. Teaching my nephew how to create stop-motion videos on his iMAC takes some effort. Android is fine for me. It "just works" as they say.
I agree with the other sentiments about "free".
I've had no-contract Verizon for two years with free (second hand free, not pretend free) phones. Prior to that we used Boost Mobile for a while. Overall the service was good, but coverage was poor when we travelled to the rural Midwest to visit family. U.S. Cellular is king in those parts. Verizon roams well there too. I think Verizon just bought out some of their market.
Every carrier has good service in Houston. It is when you leave town that you discover the limitations.
My phone's power button went out a few days ago. To "upgrade" phones was going to cost us $25 more per line under the new contract. Be very careful of "Free." The phone I picked out would cost me $600 over the 2 year contract.

Late observation, but since you've been using an Android based device, that would be my recommendation for whatever you replace your older phone with...you're already in that "ecosystem" and even state at least one app you want to continue to use. All of the current Android phones use v4.x...v2.x is major, major old!
Me...I'm an iDevice guy with years of experience and investment. It's unlikely I'd move from iPhone for exactly the same reason I suggest you consider staying with Android, at least if you have any investment in apps and media. If not, then it's work considering a switch IF you like the alternative.
