They are definitely the third most powerful.
exactly. and having left t-mobile for at&t when the iphone was released, and returning to them in 2013, i can say that their service is in no way inferior to at&t's, at least in nyc. but the perks i get are amazing in comparison. anyway, not sure what my point is, i guess that they've been pushing vz & at&t to be better or less expensive this whole time, and i sincerely home that won't change if they merge with sprint.
