I followed everything sprint said in pre ordering the iphone 6 plus. I waited all night till morning to try and pre order a phone that the website keep kicking me out everytime i tried to order. So i did it i ordered it 5 hours later. If i have to wait 4 to 6 weeks for my phone i believe me and my family will switch phone carriers...... Im sad to say it since i been a member of sprint since 2008 when i first joined army.
When I left Chili's after getting my 6 plus from the Sprint Store I ran speed tests..... I caught a glimpse of Spark 51.30 mbps down 26.52 mbps up. Coverage is very spotty, it was near a police station in Downtown Tampa. So the iPhone does pick up Spark, good on finding a location with it!
