I need basic market research on consumers who buy cell phones and
calling plans online within the USA. I need to know answers to the
following questions applicable to selling cell phones and calling
plans through a web site. Answers sought should be specific and not
generalized. Their sources should be cited as well.

1.	What are the various market segments and what is their average age,
financial position, gender (i.e. teenagers, aged 13 to 19, and salary
bracket, female/male?)

2.	What are the best resources online for cell phone user/owner demographics?

3.	What are the top 5 backend up sells that competitors are using to
increase the value of a customer (i.e. complimentary products and
services?)

4.	What are the primary factors that influence, motivate, and cause a
customer to purchase a cell phone and calling plan online?
