The bottom one is for the 8830m variant which has a hardware id of 0x06000E04.
The standard 8830 has a hardware id 0f 0x04000E04.
It would be nice if the service providers/manufacturer would come clean on these "refreshed" models, which also include the 8330m and 8130m.
Something has changed within the hardware.
There has been some speculation that it's related to the HAC hardware upgrade - https://fjallfoss.fcc.gov/prod/oet/f...ive_or_pdf=pdf, the requirements of which are summarized here - http://fjallfoss.fcc.gov/edocs_publi...C-280525A1.pdf and detailed here - http://fjallfoss.fcc.gov/edocs_publi...CC-08-68A1.pdf
