Location Tracking on a BES

[BabyJordan]

Hello Admins

I have a question for you and any help would be appreciated

I have a blackberry curve 8900 on a BES server. I would like to prove to my employer that I was not at a certain place and a certain time

we use to have GPS in our min vans and it was easy to prove, but now that was taken out due to cutbacks within the company

My boss is not aware of any programs available, but since he is a new admin he is not very well educated on BES admin duties

Question is - Can my location be tracked live via gps or at least have a log pulled and veiwed via blackberry. Would my gps have to be turned on on the unit itself
