The only reason they are loosing customers is because they have 0 good phones, and haven't for years. The network itself is great.

Here in the intermountain west Sprint is a joke. I have been a customer for over a year (was ATT) and they coverage is minimal at best. In large cities they are great (Las Vegas, Denver...) but smaller areas like Boise they have just enough coverage to offer the service. Dropped calls and lapses in data coverage are the norm. As long as they refuse to build towers their customers will keep leaving for other providers.
