Hi, People! Please, help me. I have a BB passport with nextel since may/2016. Until december/2016, before the upgrade system, the 3G worked good. After the upgrade to 10.3.3 the 3G doesn't work any more. Do you have any idea how to fix this? Is it possible to return the old version? I tried many times ask to nextel operators what to do but none of them know about this and they don't know how to resolv it.
