Sources familiar with the matter claim that Sprint has approached sources of funding for a T-Mobile buy previously rumored in December. Sprint executives Joe Euteneuer and Greg Block met with a half dozen banks to prepare financing agreements before Sprint signals that it is ready to entertain offers. An offer for the US telecom provider is expected during the early summer. Sprint has been formulating a position to convince the FCC and the DoJ that the merger would not harm the US wireless industry.
