Chief Executive of T-Mobile USA Philipp Humm has resigned from the company, leaving COO Jim Alling in charge while a replacement is searched for. A spokesman said that Humm is leaving his position to join an unnamed competitor in Europe, and would be rejoining his family there. Originally, Humm had advised T-Mobile of his intention to leave by September, however his departure was moved forward once he informed Deutsche Telekom Chief Executive Rene Obermann of his new employer's identity, which remains unknown.
