As rumors heat up that Sprint is poised to make a public bid for T-Mobile, analysts and others are beginning to look at what the two carriers would look like if they merged.

Below is a snapshot of the network of a combined Sprint and T-Mobile, as well as a customer and financial comparison of a combined Sprint and T-Mobile against market leaders Verizon Wireless and AT&T Mobility.
