Hi Bro
Based on this URL http://www.cisco.com/en/US/docs/security/asa/compatibility/asa-vpn-compatibility.html#wp169765 Blackberry isn’t listed as a proven tested product by Cisco.
Nonetheless, I spoke to some of my buddies here in Malaysia, and according to them, the BlackBerry VPN client can be loaded on a BlackBerry and successfully establish a VPN tunnel with a Cisco ASA FW only via PPTP method, not SSLVPN, IPSEC, AnyConnect etc. This works best on certain BlackBerry models.
Version 6.0 - BlackBerry Bold 9650/9700/9780, BlackBerry Curve 9300/9330, BlackBerry Pearl 9100, BlackBerry Style 9670, and BlackBerry Torch 9800.
Version 7.0 - BlackBerry Bold 9790/9900/9930, BlackBerry Curve 9350/9360/9370/9380, and BlackBerry Torch 9810/9850/9860.
Smartphones and Tablets:
