I have used WURFL Java API (also using the web browser patch) to create a standalone application for device detection. When a user agent for mobile app is used , it returns generic web browser (or blank field if web browser patch is not used) for Android and application version as device_os_version for Apple iPhone app user agents. The algorithm used in the new api as described in new api algorithms should give correct results but its not!
Can anyone help me how to tackle this problem?
I've not used the JavaAPI myself, but I have had good luck so far getting support directly from the WURFL community forums. They have a subforum for API problems. I would suggest making a post there, including the user agent string that's giving you problems and a sampling of the source code you've attempted to use before.

Sorry I couldn't give you a direct answer.
