1.4. New Features on the i325
1.4.1. Concurrency
The i325 supports the concurrent execution of up to three MIDlets at a time. The three MIDlets
must be from different MIDlet Suites. You can't concurrently execute two MIDlets from the same
MIDlet Suite.
Only one of the MIDlets can be in the foreground at once, leaving the other two suspended in the
background. As with other iDEN products, the MIDlets in the background can still execute while
they're suspended. Now more than ever, it is recommended that MIDlets be written in such a way
that they release any resources such as files, large temporary heap storage, and threads.
