Thanks!
Not using anything low level... hence the surprise.... we actually use
it to determine if our login url is reachable; if not we work
"offline". I'll take a deeper look at what we are doing there.

My iOS app uses the Reachability sample code to detect network

When using 3G, we get to the "connectionrequired" state. What to do
then? We try a login to our web site and that fails.
WIFI works great, but we need 3G also.
What am I missing or should read up on?
If you use CF or NS (or anything build on top of that) to connect,
then it should "just work". If you are using raw BSD sockets, then
there is no way to connect other than using CF or NS.
Also Reachability isn't meant to be used to determine online vs
offline. Its meant to determine if it is a good time to try to
connect or not. Due to realities of networking it is entirely
possible for Reachability to tell you "try to connect" and to fail
completely.
Basically when using Reachability, you should always use the
callback to know when to retry any previously failed connections,
and once you get a callback that says that connection is possible,
then you should try to make the connection, while continuing plan
for possible failure.
