Yesterday I tried to purchase an app from the Store, and when it asked for payment it gave me the option of payment from my credit card, or payment through my carrier bill. I selected carrier bill, and it hung. It attempted to "authorise payment", and I left it overnight, and it was still there this morning, trying to authorise.

I then killed the app (with swipe down), and tried again, thinking I could just use the credit card option, but now the Store app doesn't work at all. I can start the Store app, and after about ten seconds, it fails with "Store not responding, Close application ?".

I've rebooted the device, and still the same behaviour - can anyone shed any light on this behaviour, and perhaps advise a way I can make it work again ? Is there a configuration file somewhere I can poke around in. Why does it still fail after a reboot - it must have saved its state somewhere - where might this file be ?

I had used the carrier bill option successfully before, probably on PR1.0. I am now on PR1.2

The carrier is Telstra (Australia).

Is there a backdoor way of installing apps other than through the store ? [it was the Personal Web Server app I was attempting to install]

Many thanks for any advice ...
