hi, i have jb 3gs 16gb, jb using blackra1n and sn0w and using with tmo. i had first activated using att sim card and then did jb and using with tmo, i am encountering couple of issues and would highly appreciate any help: 1. if the phone was activated using att sim, do i need pushfix? I have applied pushfix but I can just restore and do jb again withpout pushfix and will i get all push notifications? 2. under wifi settings, when i select my enterprise proxy we are made to select a proxy, but whenever i enter the proxy details, and click on wifi settings, the http proxy settings is lost, this means i cannot use proxy at all in wifi. i have experiencing this issue just recently, the only thing i downloaded new is backgrounder/proswitcher, would this be causing the issue? please help and thanks in advance.
