Unfortunately even after deleting the prefs and restarting, I still don't see any apps. I did successfully receive a transation though, so it's working.

Mt Gox is currently skewed significantly from every other rate. There is a library called Xchange which is what MultiBit uses. Alternatively BitPay export their blended rates:

It'd be great to have some support for exchange rates in bitcoinj if anyone wants to contribute.
