I have tried to search the forms to solve this problem but I cant seem to find anything. I have a new sprint curve with 4.3.0127 installed as my OS.
I installed the blackberry maps using desktop manager software but I can not seem to find it in the applications menu. I can see that Options for Applications that the Blackberry maps is installed running 2.20.26. Currently the GPS Data source is set to Device GPS and GPS services is set to location ON but when I look @ the Maps options I dont see anything listed for the defualt services.

I currently have an unlimited data but no blackberry data plan.

Get Blackberry Maps and Google Maps working on Beta OS 4.5

I use AT&T Navigator and Google Maps, but I tried this a while back just to see if it worked, and it did.
Not sure if it will work without a BlackBerry data plan though.
