Will the iPhone 4 be losing support?

I'm thinking of changing to verizon for my cell phone carrier. I also plan to be getting a new phone. The iPhone 4 would be free, so this seems as though it would be a good deal, unless the phone would be getting phased out. The iPhone 4s is $100, and the iPhone 5 is $200. I know that the iPhone 5 has a longer screen, so would that mean apps and such for the old sized screen of the 4 (and 4s?) are being phased out? Also, the contract would be for two years.

About the apps, no.iOS apps have the option to be scaled to suit so an iPhone 5 optimized app will work fine & display fine on an iPhone 4/4S. Hence why Apple still sells those 2 iPhones.

My advise, best skip iPhone 4.

Cause in this current world, programmers are already leaping to create apps that is more compatible with dual or quad core processors.

Time will make iPhone 4 feel slow.

Anyway, why would you choose iPhone?
Why not run to an Android like Sony XPERIA or Samsung?

For the same price, you get better specs and screen size too.
Not to say, Sony has XPERIA models that are dirt, water and smash proof.

ILostFinder seems useful. I will have a try later.
