What are the best selling cell phones for all the major wireless carriers in the last 2 years?

Justin: What are the best selling cell phones for all the major wireless carriers in the last 2 years?
I am seeking information for a study regarding the top selling cell phones of the last 18 months. I am trying to find a list that shows the top 5 or 6 best selling mobile devices (including smartphones, PDA’s, etc.) for each of the major carriers. (Verizon, AT&T / Cingular, Sprint / Nextel, Alltel Wireless, T-Mobile). I am hoping to be able to go back to January 2006 with this information if possible. Thanks!
