I know I was wondering where the current OS device simulators were until Richard enlightened me. It turns out that after OS 4.3 RIM has started bundling the device simulators for 4.5 and now with 4.6 into the JDE. They are no longer available for download separately.
I have had quite a few people ask me where the simulators are so I thought I would mention it. You just install the JDE and the simulator will be added to your machine. That way you can test your software or themes on the Bold or on OS 4.5. Obviously RIM partners already have access to a more advanced version of the 4.6 simulator but the one included inside the public beta JDE is not that bad.
Or if you are just like me you can use the 4.6 JDE Beta to get a chance to play around a bit more with the Bold 4.6 OS.
Thanks again Richard for letting me know!
