I have the same problems when they throttle my data.... call them and ask if they have a section 6 violation on your account. its exactly what happens to me... some apps like XDA developer app and speed test wont work at all.... just for fun call and ask or what did they say when you emailed them?
I find if I keep trying it, it works... like 4 times... this happend a lot on my iPhone when they throttled me until I cut the proxy... anybody confirm this?
First thing I will do is kill their proxy when I can root... the Root they have out right now is test or beta so IM not gonna touch it.... but full root with CW and SU should be soon... will see then huh?
what I will do is use the BYOP sim I think so they cant cry about me modding.... look on the back of the box they try and scare you about modding this phone...
