How can I store data in a mobile widget (JIL/W3C). Is Widget.setPreferenceForKey() the only option?

A:
You can store small-size data using Widget.setPreferenceForKey() method and retrieve it with Widget.preferenceForKey(). There are no other options at this moment.

Not really different to Radu's solution, but it allows you to store data in a persistent way. So your widget can store data on many different devices and in the browser.
You can read about it here: http://tinyhippos.com/2010/04/11/mobile-widgets-persistence-cross-platform-wrapper/
Hope it helps.

Yes, what Radu sais, it's the only option, if you want to persist the data. Keep in mind, though, that it's a key/value store and that keys and values are strings. To store objects, you'd need to convert them to/from JSON.
Documentation sadly is rare on this, but this is a good point to start: Opera dev
