What do I need to be aware of when developing applications that use BREW app-directed SMS messages?
In the real world (commercial handsets, not test-enabled handsets), an BREW-directed SMS message will be sent to a BREW application only if the app-directed SMS is sent from an carrier-authorized gateway or from within another BREW application (using ITAPI_SendSMS, available in SDK 2.0 onwards). This is done for security reasons, and ensures that the sender of the SMS is a trusted source. In order to facilitate development of applications making use of this feature, we have allowed BREW applications residing on test-enabled handsets to receive BREW app-directed SMS. If you wish to use App-directed SMS on commercially deployed applications, you should contact your carrier for special access to provide this capability.
