Here are a couple of unresolved issues.

1) It is not possible to seamlessly move from Wi-fi to carrier and vice versa with iopenvpn running. Hence, it is recommended that
a) If you are connecting via wifi and running iopenvpn exit out of iopenvpn before leaving wifi coverage.
b) If you are connecting via carrier and running iopenvpn, put wifi off.
2) If you have left iOpenvpn on, and you are taking a break from using your iphone, when starting again, it is recommended that you press the iOpenvpn icon to see if there are any error messages. If there are none, you can then press ignore button, and continue to surf. Right now, the issue is that if openvpn disconnects due to any reason, no messages appear spontaneously. They will appear only if you press the iOpenvpn icon. Of course, if you are using iphone you will see the messages in some form or the other.
