I updated my iphone to 4.2.8 and jailbroke the device before installing the official release. The funny thing is that after I was done installing it, the iphone reverted back to the way it was before I got it flashed. I updated to 4.2.7 and everything was breezy, the phone worked with metro from the jump, but with this one, it erased all my settings. I've tried plenty of methods to get it back on metro, but the furthest I've gotten is to installing prl 2004 and dialing *22804, but after that I download the roaming lists and I get a message saying that my phone has been activated and that it is up to date and then nothing. Now, I've tried making calls out of it, but I get the "msn 02, the call cannot be completed as dialed, please check the number and dial again" I've tried putting a 1 after the area code and nothing. Everything is correct on the dialing. I can call metro service, but I can't call no one else, or text. Can someone please help me?
