I just finished these steps and now it shows 4G but when I ran a speed test at my house it gave me the same test of 16 mbps over and over again so question is by doing these steps do they really give me 4G. I've got the iphone 5 factory unlocked USA version and it showed 3G on my device and had good speeds for example at my house it hit 16-19 mbps then I did these steps and they do the same speeds.
