The cellphone posts (see below) have been sorted, finally. This ranking is by no means definitive in any way. The phones have been sorted into two major categories - unlocked and no contract phones.
What I did was to rank them according to their specs, giving heavy weight to CPU, RAM, and storage. You'll notice that they're clustered in groups for phones with similar specs.
Also, note that I separated phones according to their OS. With these no contract phones, the OS you buy is the OS you're stuck with. Manufacturers rarely upgrade these low-end devices. So take that into consideration if you desire certain features.
