I don't know if you guys know that but if you have t-mobile it comes with unlimited data but after you go over 1GB it slows down from 50mbps to 256kbps but even after it slows down certain music apps and also the speed test app have access to the 4G speed because when i run the speed test app it tells me that my speed is 50mbps when in reality it is 256kbps so I was wondering since some apps have access to high speed data isn't there a way to hack my phone so that everything on my phone can have access to the 4G speeds.. My phone is jailbroken too
