If you have :

• a Windows Mobile 5 or 6 device, then NO Problem, just use the Windows Mobile application!
• a BlackBerry device, No Problem, just use the Mobile Java application (all BlackBerries running software 4.2.1 or newer are JSR-82 compliant). You can first use the GS-911Verifier to test your BlackBerry's JSR-82 compliancy...(the native BlackBerry application has been discontinued)
  
• an iPhone, then it will NOT work currently - see the related FAQ !
• a Normal phone that runs Java applications and has bluetooth (like most typical Nokia, Sony Ericsson, Samsung etc.) - These must be JSR-82 compliant (not all are!) - you should check your phones compatibility with GS-911Verifier (read below)

If you have a normal phone that can run Java applications (this means it is NOT an older BlackBerry (most new BlackBerries can run Java midlets) or Windows Mobile 5/6 device, but your typical Nokia or Sony Ericsson for instance), then you have to check whether it is JSR-82 compliant. This is a prerequisite for the application to run!

You can download the GS911Verifier.jar from the downloads section. This Java midlet will simply test your phone and tell you whether it is suited or not - most are ;-) . Once you click the [Test] button, the status will be shown as one of the following:

• "Your device is capable of running GS911!" (good on you.. you can run the Java midlet on your device!)
  
• "Bluetooth api not available - Java VM is not JSR-82 compliant". (If the API could not be found, your phone is not JSR-82 compliant, and it will not work on this mobile device.)
• "Bluetooth api available, but not allowed by Operator". (Some phones are crippled by the network operator (typically Cingular/AT&T - we have had no feedback on Verizon devices yet), this is one of them, and it will NOT work on this mobile device. We are currently in negotiations with Cingular/AT&T to get the application signed which in theory should make it work ;-)

• Bluetooth api available but not allowed by Operator. What does this mean?
