T-Mobile will only offer iPhone if price is right
Other

T-Mobile COO Jim Alling offered up a response to all those who have been wondering why T-Mobile isn't carrying the famous Apple iPhone. Speaking at the Morgan Stanley 12th Annual Technology, Media & Telecoms Conference, Alling says that T-Mobile simply wants the "economies to be right." That is, they don't want to pay too much for iPhone, much like what AT&T and Sprint did, in order to sell it. So unless T-Mobile and Apple can work something out, a T-Mobile iPhone may never see the light of day.
