Look, we needn't tell you that things aren't exactly kosher for Sprint right now. SK Telecom just said "thanks, but no thanks" to a potential relationship, it managed to post a net loss of $326 million in Q3 and it's staring down the barrel of a $1.2 billion class-action ETF suit. All that considered, the sudden and apparently unplanned departure of the carrier's head of CDMA isn't apt to help things. John Garcia, without any (public) rhyme or reason, has decided it best to not clock in on Monday, and at the moment of his leaving, the company had no comment on the situation. Bigwig Keith Cowan has been chosen as the interim replacement while it searches for a successor, and in related news, Bill Morgan (SVP of brand management) will begin reporting directly to CEO Dan Hesse.
