Some observations about coverage around me. It looks like the former Centennial Wireless roaming in northern IN is being replaced with native coverage right now due to the huge number of new towers shown north of Indy. It's good to see such a large T-Mobile expansion in rural locations. There will also be new coverage coming soon on the I-69 extension between Evansville and the Crane Naval Center. I would be shocked if T didn't cover the "new" interstate. Hopefully it will be 3G/4G. Part of this new interstate route currently has no coverage at all in rural Pike County, IN.
The maps don't seem to show the Alltel coverage in S. IL being a "service partener." It just shows it as the old grey roaming. Probably not updated yet?
Finally, the partner coverage is now more accurate. In areas where it used to be white, and where I did roam on far distant AT&T 850 MHz towers, it is now correctly shown as covered.
When I was on it last night at 1am it was really glitchy showing pink in portions of the map with the new set up and it was also really slow, maybe they will make it more efficient over time. Im surprised they haven't gotten compass working yet.
