I've been considering switching to Sprint for a while now. I'm wondering how their new Spark network is working. I used to go read Sprint.com's message boards and see nothing but complaints from people who had nothing but issues with Sprint. In recent month's the complaints have really tailed off. From what I understand, the iPhone 6/6+ are the only iPhones that are compatible with their Spark Network. How is the service? Is it better or the same as their previous generation LTE network?
