The revolving door at Yahoo! kept spinning this week as announcement of the departure of two more senior executives surfaced, this time from the mobile division.

According to the Washington Post, Steve Boom, senior vice president of Connected Life, and Gary Roshak, vice president of mobile advertisers and publishers, are both leaving the company.

Boom will leave at the end of September after the CTIA I.T. and Entertainment Show in San Francisco. Roshak has already left and been replaced by David Katz, formerly vice president of corporate strategy for Yahoo!.

No word on next steps for either departing executive.
