JAM - BT Handsfree and speakerphone simultaneously?

[SorAV]

On my JAM at connection BT Handsfree (tried different headphones) simultaneously work Handsfree and phone speaker with microphone.

Advise to correct as it that worked only BT handsfree.

On my imate JAM, it does same thing. But never happans to my Dopod 818 (same as JAM except in Chinese ROM).
BTW, my JAM has been flash to Dopod ROM. I am not sure it happens before or not.
