BlackBerry GPS Tips
If you are having trouble getting GPS data you should first check to make sure GPS is enabled on your phone.
You can check this by going to Options->Advanced Options->GPS.
Make sure that:
"GPS Data Source" is set to Device GPS
"GPS Services" is set to Location ON
"Location Data" is Enabled
"Location Aiding" is Enabled
Also realize that GPS needs direct access to the GPS satellites. This means that if the phone is in your pocket or purse or if you are in a building it may not be able to get a signal from the satellites.
Also to avoid sending redundant data TrackWary will not send GPS data if its position hasn't changed.
