shadytel described

ShadyTel provided a local GSM network for unlocked phones at ToorCamp. Here, one of the ShadyTel campers describes the setup to someone from the reservation community and a few other geeks looking on. When they were setting up, I asked some of them how it was going and got an instant education in how GSM networks need synchronized clocks, and (if I remember what they said) it may even take hours for a crystal to reach the right temperature to sync with GPS satellites. I asked "What's the quick and dirty way to do this?" They said "This IS the quick and dirty way."
