Na kraju će biti da su oboje u pravu:

Android ima mogućnost lociranja putem wifi mreža i triangulacijom. Kombinacijom ove dvije mogućnosti možeš se navigirati i bez pravog GPS signala (bit će grbavo i loše, ali je moguće). Ono što mobitel skida preko neta su ipak podaci o poziciji satelita (SUPL standard):

With A-GPS, the mobile device receives information about the satellites’ orbit, frequencies and functionality over the wireless network. As a result, it can detect and analyze even weak satellite signals at lightning speed. The A-GPS technology uses the radio link between base station and mobile devices to transmit this “assisted” satellite data within a matter of seconds, thus saving time and battery power compared to traditional GPS systems.
