Did a restore to same version 4.1 then used greenpoison to JB and phone had no service after that. Tried restoring again to fresh 4.1 but still no luck. I'm with AT&T. Any help will be greatly appreciated
The problem turned out to be that I had ran the JB with a different simcard inside cuz I had to swap them out for awhile. I reran the JB again and it found service again.
