This app is aimed at providing two important pieces of information:
1. The name of the current CDMA network (Sprint, Verizon, etc.), even when roaming. It's very possible that I've missed it, but I haven't found another app that displays the name of the network when roaming.
2. The data type for the connection (3G or 1x).
This is not supposed to be some revolutionary app, but just a tool to determine what roaming network the phone is on. It can be helpful when determining what PRL and roaming mode are best for your area and phone.
I didn't bother adding signal strength, tower locations, etc, because I don't personally find that data particularly useful. I'm generally only after the owner of the network and the data type.
Example: I've seen cases where a phone will roam onto network A when in "Automatic", but it will roam onto network B when in "Roam only" mode. This app is a quick way to find out that network A is actually Verizon, and network B is USCC.
Let me know if you want anything added, or if this app is even remotely helpful to your situation.
