I went to ND from FL...2,400 miles one way then back through SD...5,300 miles total. I was using roaming services through Verizon for 70% of the trip and got data access only while i was already back to FL...even got some areas with no services at all!
Data through WiFi (in hotels and buildings) did work but Gmail was not synchronizing until i came back to FL. That was the big surprise, i though sync could happen through WiFi but it didn't....a glitch within #2 v1.4?
