O2 seemed like it was going to be my first smartphone.  I live in a rural area and iphone would not work.  Verizon is my only option for best connection.  Seems like a common theme.

Now I am learning about android.  Mostly what attracted me to O2 is the look and customization. Over the next two years I want to be able to change up the look and function.  My  verizon phones I have had so far quickly became boring.

I am new and looking for advice.  Which is my best direction long term?
