I understand that there is nothing public about the workaround. Yet, you were able to get the details? Am i to assume that you work at RIM?
The fact that RIM says it exists doesn't mean much.
It can exist and hinder the quality of the current system - i am sure we would all agree that this is unacceptable. RIM's great push email is what makes it superior - changing the system could cause problems.
Or it could exist and still violate the patent. Therefore, it would be useless.
The only way a workaround matter is if it exists and does NOT hinder quality and is NOT in violation of NTP patents.
In order to determine whether these conditions are true, we would need to know more about the details.
