The title pretty much says it all. Sprint kinda sucks in my area (about 1 bar of 3G on my Nexus 5 outdoors; I can get 1 bar of LTE for a minute or so if I toggle airplane mode). So, I'm concerned about how good (or poor) the iPhone 6S or 6S+'s RF performance is. Any thoughts?
If that is true, it could also help the New T Mobile as Dish's spectrum could possibly be shared as well. Dish will take a few years to get enough of their own towers and equipment to run on their own.
