Alright, so I've had my 3G jailbroken for a month or so, and everything is all fine. I live in Australia and I'm using the Optus carrier, So, today, I went into Settings and and Carrier, I saw it was on Automatic, and for some reason I thought I would click on Optus 3G. I notice I can't text or make phone calls now. After awhile a popup comes up telling me my cellular data has been lost and to select another data, uh oh... so I just chose Optus. It started working again, but then the popup came up again. The signal bar and name is still there, but I can't make calls, every so often I might be able to make a call, but not always. And I can also sometimes send and recieve texts, but no all the time. The Carrier options in Settings are; Automatic Optus 3G Optus Telstra 3G Telstra vodaphone australia So, even though I've done so much to my Jailbroken iPhone, I decide to restore. Now first, I restore to a custom 2.0.1 firmware. Same problem, and the other carriers are still in settings. And yes, I made sure I didn't unlock my phone for use with another carrier. So, I try using iTunes to restore my phone. After it's done, it still has the problem! And the other carriers are still there! I REALLY NEED HELP!
