Here are the 2007 overall rankings (for Volume I, that is):
* Northeast: T-Mobile
* Mid-Atlantic: T-Mobile and Verizon Wireless (tie)
* Southeast Region: Alltel, T-Mobile, and Verizon Wireless (tie)
* North Central Region: AT&T, T-Mobile, US Cellular, and Verizon Wireless (tie)
* Southwest Region: T-Mobile
* West Region: T-Mobile
Looks like this is just for Q1, but it’s nice to be on pretty much the highest ranked carrier in the US. It’s even nicer to be working for it. Read here for more details.
