so I have a firmware 3.1.2 3g jailbroken iPod touch with fring, backgrounder, and gvmobile (google voice)apps on it among others. I have both google voice and fring set to background when opened. It was working for a while to call people using gizmo 5 in fring and gv mobile but it stopped working. I can still recieve calls with it but I can no longer place calls. If I use my computer I can use google voice on it to call my fring but I cant use my gvmobile app to call my fring app Please help. I don't have a cell phone and I really need one but I don't want to buy one.
