We're working through wireless deployment issues with support right now. We've had really mixed results, and not enough success to make me confident I can do a large-scale wireless push of an app.
The main problem we see is messages in the POLC log indicating that "request has already been queued" for a particular user. It seems like a failed wireless deploy will result in subsequent deploys failing. There is a Known Issue KB doc on this particular situation. http://www.blackberry.com/knowledgec...28047&vernum=0
