Hi cmcluckie, JohnnyCanuck,
Thanks for your interest in Map My Tracks and sorry for the delay.
We are working hard to resolve the issue with some blackberry handsets aquiring an initial GPS location and should have a solution soon.
I agree, Fire Eagle has really taken off and we believe that using Map My Tracks to share GPS locations is one of the easiest ways to use the service. That said, as you rightly point out, there are some issues we are aware of on a minority of handsets but rest assured that fixing these issues is our highest priority at the moment.
Please bear with us and we shall release an update shortly which will let blackberry users join the party.
Regards,
Rob
