Hi!
AGTL only relies on the built in GPS receiver routines, it doesn't send or receive any gps related stuff. It is correct that the phone uses AGPS to get a faster fix (see this forum or google for mor information). This is why there's data send and received.
As OVI maps uses the same routines, it is unlikely that starting it will speed up signal acquisition for AGTL. On the other hand, OVI Maps can sometimes display a fix when AGTL doesn't. This is because AGTL is pickier about the quality of the fix. The first fix is always a very rough estimate of the position based on the current cell tower. As this is useless for geocaching, AGTL filters those fixes out.
I hope this clarifies the situation a bit :-)

I didn't think that the application would make a difference to the speed the GPS receiver locks on, but I would be interested if it could make a difference because on the last couple of occasions I've used AGTL I have had to wait quite a while for the GPS to lock on even though I have had network connection enabled.
Assisted GPS (A-GPS) uses GPRS to find out the location from the closest mobile cell towers and information of relative satellite positions to enable the GPS unit to lock on quickly. If the GPS receiver has not moved far it kind of remembers its last location and can lock on pretty quickly without assistance, but if the GPS receiver is moved to a new location it will wait until it has a clear signal before it locks on.

The arrow isn't a compass, it is pointing towards the cache that is chosen as target.
