This application does not work on all BBs listed on their web site. The admin says it requires a version of BB OS that includes JSR-82. The error is : Error starting amaze_4_000: Class 'javax.bluetooth.DiscoveryListener' not found.

Admin answer:Usually, this error means that the phone doesn't support JSR-82. This JSR is what enables bluetooth connection at the same time that a JAVA application is running. In BlackBerry's case - the support/not support specific JSR depends on the software version of the phone and not on its model.

I am running the latest version OS for my 7130e and the 7130e is listed as a supported device on Amaze"s site. There may be other phones with pre 4.2 os that even though listed on the amaze site are not supported.
Bummer!
