1. Cell phones have a much larger margin of error
2. Triangulation will tell you your location w.r.t the towers, but not w.r.t map. If you started mapping, it would be a herculian task
3. It would work only where there is network.
4. If due to terrain you get signal from a far away tower you will get wrong info
5. Satellites are already up there. Reciever is a cheap and low cost solution.

If you want to see the power of GPS, look at the TBHP meet report. By 7:30pm evening the pics will be up again, including the exact track taken by the noida convoy.
