H4 Extension approved after H1B


I am requesting your advice on the following case details:

H4 Extension of stay petition was received by USICS on 26th June 14.

H1B Application got approved on 04th Aug 14 after RFE, and is valid from 01st Oct 14. (I797A indicates that: The petition and change of status have been approved)

H4 Extension of stay petition got approved on 15th Oct 14.

Please advise what is the final Immigration status in this case – H1B or H4? Will there be any issues If SSN is already received, which was applied after 01st Oct 14? If the final immigration status is not H1B, what needs to be done?
