On T-Mobile: <i>A merger with Sprint-Nextel has been mentioned several times. The combined company would have a customer base about the same size as AT&T or Verizon</i><p>After the difficulties of merging with Nextel (competing corporate cultures and different networks), I doubt Sprint would be eager to see history repeat itself. To have to run possibly 5 different networks (CDMA, GSM, iDEN, 4G/WiMAX, LTE) would be too much to handle.
