I have got a nokia 6680. I have also got a vpn installed (from nokia's site).

VPN problem: The vpn connectivity is very unstable. It says vpn access point activated and with in a minute or so the access point deactivates. Sometimes (only occasionally) the vpn connectivity stays long without deactivation.

Reboot problem The mobile reboots often, I suspect particularly when I try to connect to vpn. Sometime the phone freezes and I cant even switch off. I have to only remove the battery to switch off.

Please suggest.
