The iPhone 4S supports a Russian version of GPS known as GLONASS, an update to Apple's specifications page shows. The country only just launched the last of 24 satellites needed for global GLONASS coverage at the beginning of October. GLONASS first became fully operational in 1995, but a funding crisis crippled the ability to keep working satellites in orbit. Improvement in the Russian economy since the 2000s and interest from ruler Vladimir Putin has allowed GLONASS to come back to life.
