I have an iPhone 4, and my son a new 4S for Christmas. Mine is always on 3G and his on 4G when there's no wifi. Two questions: 1) was iPhone 4S the first iPhone to allow and use 4G cellular? 2) is there any change of settings that would allow my 4 to use 4G?

The first iPhone with a cellular chip/radio capable of utilizing the LTE network was the iPhone 5, not the 4S.
Neither an iPhone 4 nor a 4S can be made to utilize the LTE network; that would require a chip/radio they do not have.
Keep in mind that "true" 4G is not what the sales-droids claim it is:
In March 2008, the International Telecommunications Union-Radio communications sector(ITU-R) specified a set of requirements for 4G standards, named the International Mobile Telecommunications Advanced (IMT-Advanced) specification, setting peak speed requirements for 4G service at 100 megabits per second (Mbit/s) for high mobility communication (such as from trains and cars) and 1 gigabit per second (Gbit/s) for low mobility communication (such as pedestrians and stationary users).
Even now, no US LTE provider gives you even 100 Mbits/s, let alone ten times that.
