In a situation where a BlackBerry application is installed to a user’s device via OTA (BIS), and that application has a “Check for updates” button, one simple approach would be to launch the browser with the address of the .jad file which would then present the user with the “You have version 1.0 installed, would you like to download and install version 1.1?” dialog. But even if there are no updates, the user would get the “You have 1.0, would you like to replace it with 1.0 dialog”, which is a hassle and is meaningless.
Is there an better method for doing this in a more seamless manner? For example, are there accepted ways for the application to check the server for an update (with user’s permission), inform the user if an update is available, and install the update OTA without going through the browser/jad/ota/replace/restart device loop?

Thank you.
One way would be to fetch the JAD file using an HTTP connection in your app, parse for the version available on the server and only launch the browser if there is a newer version available, or after additionally asking the user if the upgrade is desired.
There are elements of the API that would allow you to also fetch the COD file(s) and install the modules yourself, but that seems like just increasing potential bug space unless you really need to avoid using the Browser OTA install.
