I believe TCP port 3101 is a registered port for BlackBerry Enterprise Server traffic. Any idea why the name shown for the port in Wireshark is hp_pxpib (HP PolicyXpert PIB Server)?
It is officially registered to hp-pxpib. From the services file in Wireshark (which is pulled from http://www.iana.org/assignments/port-numbers) : 

hp-pxpib        3101/tcp   HP PolicyXpert PIB Server
hp-pxpib        3101/udp   HP PolicyXpert PIB Server
