Is there a way to do an overlay between 2 points (coordinates are known) on BBMaps?
I would like to do something similar to the purple think overlay that comes when you look

In the 4.5 release, we have released a new API called MapField (net.rim.device.api.lbs.MapField) which would allow your application to take over full control of the BlackBerry Maps application including the ability to overlay any graphics on the map that you would like.
There is a sample in the 4.5 JDE called MapFieldDemo that outlines how you can leverage this new capability.

Note that MapField involves embedding the field within your application. If you're just looking to launch BlackBerry Maps, drawing a the purple line from point to point, this function can be accomplished using the GetRoute XML tag in your Invoke call. Please see the following document for more information.

Is there a way to determine if BlackBerry Maps is actually installed and running on a device? AT&T/Verizon do not install the BlackBerry Maps Application and if people add it later then it still doesn't work. If one invokes the application it gives a null pointer exception. Can we determine ahead of the Invoke that it will actually work?

Thanks, the map field demo works well for me.
Two followup questions:
1) Can existing devices upgrade to 4.5 version?
2) If not, do you have an idea when devices with version 4.5 hit the market in the US?
