I got good coverage with sprint and I usually 4gb of data , but what I have notice is the android phones get better download speeds on the same network, my wife has a nexus s and gets better speeds (WiMAX off ) my brother too wit the epic 4G , now I thought maybe is antenna issue , but then my friend has a droid x and my other friend and iPhone 4 on Verizon , and the droid has better speeds then the the iPhone 4 and there both in the same spot , I try with my friend 3GS and his infuse and got better speeds too but I think the infuse is "4G" so idk what's up with that
