This should not be. The standard idle tear down timer for the connection for both IPv4 and IPv6 is 60 minutes. When i was using the N900, i had to hardcode the T-Mobile IPv6 DNS server into the /etc/resolv.conf since the using nameserver 127.0.0.1 would result in some DNS queries going over IPv4 .... and only the IPv6 sourced DNS queries result in IPv6 google content ... if you are not actively pulling IPv6 content like Google over IPv6, the idle timer will kick in and the connection will drop.

So, my suggestion is hard code "nameserver 2607:FB90:BEEF:A::1" in /etc/resolv.conf to make sure all your DNS queries go over IPv6, which will keep your IDLE timer in check, .... it will also ensure the Google content including youtube comes over IPv6 ... DNS queries over IPv4 will not result in Google AAAA IPv6 DNS records.

If you are especially curious, tcpdump gprs1 to see what traffic goes over that interface.

Ps. this was when using the dual-stack method from garage. The new package that one of the folks put out for IPv6-only sounds very promising.
