A spokesperson confirmed to us that the launch of the enhanced network in these new areas brings T-Mobile’s total covered for iPhone compatible 1900 MHz PCS spectrum to 100 million people.
Internal tests of unlocked iPhone 4S devices running over 4G (HSPA+) on our 1900 MHz network recorded on average 70% faster download speeds than iPhone 4S devices on AT&T’s network. Savings based on comparison of T-Mobile $69.99/month Unlimited Talk, Text and Data plan against AT&T Unlimited Talk, Text, and 3GB Smartphone Data plan.
T-Mobile also said more enhancements to the network are on the way to “Boston, Chicago, Los Angeles, the New York metro area, Philadelphia, and San Diego,” with many customers already experiencing unlocked iPhone “speed sightings.”
