Until Sprint stops seeing us as their sibling whom they have to compete with, we will never get any flagship devices anytime close to release.
They always keep us from having a competitive edge. Like how they did away with full unlimited data. How they never allow us newer model phones. Heck, even how they train their Sprint employees to avoid mentioning any association with us.
Until Dan Hess realizes that we could be a valuable asset and shouldn't be disregarded, we will always be a step behind competition. I'm hoping Soft Bank will push some changes down that ladder. I've got my hopes!
