FanOfSkynyrd; hang in there, we are starting to s see some improvements in the area, I've been keeping track and constantly monitor speeds around town. Just remember that just like a vehicle, you can't change the oil and give it maintenance while its running. Same applies to cell towers, so if you are experiencing some severe outages or severe internet speeds, it might be that the towers are being maintained or upgraded. I'm starting to see some progress at network.sprint.com. You can also keep track and trace progress there.
We all feel the frustration.
Edit: areas that have significantly improved (take significantly with grain of salt; that just means it is way better than what it was) are the areas of Yuma Palms, MCAS, Airport, Somerton AZ, Ave B North East of 20th street, Down Town Yuma by the court house. I get download speeds from around 2 or 300kbps up to 1200 kbps depending on the time of day.
