Installed the Ovi store version for a quick play and everything seems to work OK.

Had a bit of a strange issue on first reboot when the program wasn't set up with the standby display coexisting/merging with the Meecast icon even though I hadn't enabled it. Same went for the notification option - I had to enable and disable it to stop it popping up.

The Billboard integration works perfectly :-)

One suggestion while thinking about my upcoming trip. I'll probably use some PAYG data which I don't think will trigger any updates in USSDBalance if my understanding is correct.
Would it be possible to add an option for an interval for automatic updates, say every 30 mins or 1hr to avoid burning through too much data without realizing it?
