What assisted GPS are you talking about? Since when does Leikr have assisted GPS? Assisted GPS is using GSM along with GPS, so you if you are saying it has AGPS you are wrong.
P.S. I keep thinking it was a big mistake getting this device and supporting the Leikr project. I had problems iwth my first and and had it replaced, but using the second one is just as much a pain. It adds so much jitter to my workouts, that it should not be considered for anything else but heart rate and time tracking.
