Hey I got the new official rom which is great! Noticed in my programs section there is a app. sprint navigator. ever since i got the new rom it finds gps satellites really fast around 15-20 sec. most of the time like most here have posted..the navigation app is really nice and has voice notifications..just want to know if sprint charges for this? i have the simply everything plan..if they DONT charge then i would suggest all of you using the sprint nav. app...does everything i need it to do..
