I have installed on my Sony Xperia ST23i the HSBC Fast Balance app. It works perfectly when I set it up at home connected to my Wi-Fi. However when I am using 3G it refuses to connect, I was out at Asda yesterday and I connected with the Asda free Wi-Fi but this out would still not connect.. All that happens is it returns the error, "Service Unavailable". Doing a search on the Internet it seems that this is a problem that other people are experiencing, but there is a substantial number of people who have no problem with this app.

Has anyone got any suggestions what I might be able to do that will make of this app work? Some suggestion elsewhere was to delete the proxy and I tried this and stop the whole phone from working.
