What are the prototype SDKs?
Prototype SDKs are meant for developers, who are targeting future devices. The prototype SDK contains a number of APIs which are not yet implemented on any device, but which will be available on future devices. With the Prototype SDK the developer can start developing his/her application before the devices are launched, so the midlet can be distributed to the marketplace earlier. The emulators of these Prototype SDKs are based on reference implementation of future devices, not on real device / platform software like in Platform SDKs. Hence the implementation of UI and new APIs might not be exactly the same as on real devices. Hence, always test your application on final SDKs and on real devices.
