One problem that I've always had using PodTrapper (running 2.6.9 currently) is that when I use AT&T Navigator (aka TeleNav) while listening to a podcast in PodTrapper the audio is redirected from bluetooth to the device speaker. If I force the output back to bluetooth, it quickly reverts back to the device speaker. That problem also exists with the new TeleNav application called OnMyWay (http://appworld.blackberry.com/webstore/content/6957). I've tested this issue while playing music through the blackberry media player and it doesn't seem to be a problem.
