It’s been a long dance between Sprint and T-Mobile, but it looks like fate has finally had her way. The two companies announced on Sunday that they will, after all, merge into one venture, with T-Mobile looking like it is firmly in control. That’s significant for a number of reasons, with the most important being that T-Mobile has re-imagined the mobile market, driving service innovation and growth, while Sprint has a terrible reputation for managing mergers (Nextel anyone?). Of course, this deal still needs to get the blessing of both the FCC and the DoJ; and consumer advocacy groups will likely be screaming from the rooftops about how this merger could drive consumer prices upwards due to less competition, leading to potential challenges.
