Are you saying widgets can update faster than 30minutes? Polling?
public int updatePeriodMillis
Since: API Level
3<http://developer.android.com/guide/appendix/api-levels.html#level3>

How often, in milliseconds, that this AppWidget wants to be updated. The
AppWidget manager may place a limit on how often a AppWidget is updated.

This field corresponds to the android:updatePeriodMillis attribute in the
AppWidget meta-data file.

*Note:* Updates requested with updatePeriodMillis will not be delivered more
than once every 30 minutes.
