I've created a number of "MyMaps" w/ locations in google earth on my PC.
Google maps is also on my BB, however, this works with favourites created on the BB.
Is there a way to access the "MyMaps" content on my blackberry using the gmaps application?

OK.....I found the solution myself

Although not 100% ideal....there is a way to get your maps + locations build in googlemaps on your BB:

groups.google.com/group/mymapsmobile

It worked for me!

Enjoy
