I followed the suggestions at Google here
but they did not appear to make any difference.
I launched the app to get the exact error before posting this plea for help and initially it failed at '4' as usual with the "Network Failure" error. I then relaunched and voila, the was app now working, very bizarre!
I wish I knew what (if anything) I did was the solution. Now all I need to do is get Opera Mini working.
