Anecdotally speaking, cell phones have appeared to be pretty saturated in all the developing countries I've been in. I bought my current phone for about $55. It's got a quadcore 1.3ghz processor, 512MB of RAM, a decent screen but a mediocre front and back camera. It might have some backdoors in it though, as it's got some software I can't uninstall without rooting. The plans, minutes, and internet bandwidth in developing countries have been far cheaper than say Verizon's (perhaps no longer available) plan for 1GB of data for $40. The plans range from about $2 for 1GB in some countries to $16 for 1GB plus a chunk of talk and messaging time.
