In the 2 years that I was on my old Prevail I never recieved a message from Boost about data usage, it was rooted, CWM, ROM and Kernal 3.68 and Open Garden wifi, I would be on it for 8 hours a day every day using the internet through my laptop, with my new Prevail, 2nd day it was rooted, CWM, no ROM or Kernal yet, but I received 2 messages from Boost telling me that my I had used 85% of my data usage for the month, they give you 2.5 gigs of data usage, if you go over they cut your data speed in half which was my 3rd message. It still works, just a lot slower. I'm waiting to see some of the same people who worked on the old Prevail start to work on the new one, they did outstanding work on it and I really miss my old one, still works, but the USB charging port died and I have no way of fixing it.
