Just read this in a forum post (Swedish, sorry ’bout that), and simply had to tell you.
In the Stocks app that comes with the iPhone, you can add in a number of other things than the most obvious, like this:
Add the exchange as a suffix. For example TLSN.ST results in the share price of TeliaSonera on the Stockholm exchange. The price and graph will be in Swedish Crowns.
The OMX index can be added as: ^OMXSPI
Even currency exchange rates can be added with the base currency followed by the target and then the string “=X”. Examples:
The first one will show the current exchange rate as Swedish Crowns per US Dollar. The others follow the same pattern.
Kudos to signature sebastian_r on the 99.se forum for this info. It’s just so damn neat…
