After a unsuccessful flashing of Semaphore 1.0 kernel for Slim ICS, I lost my recovery access. I tried to flash an old 2.3.3 rom (XXJVH I think, official nordic firmware) with Odin, but it failed several times. Then I managed to flash an XXJVU (European value pack) rom, but phone couldn't recognize my SIM card. I tried to flash JVH again, and it failed again. Then I reflashed XXJVH, and now my SGS would recognize SIM card, but all the APN settings are gone, and I can connect to internet only with wifi. I'm planning to flash CWM to my phone and then Slim ICS again, but will the APN settings be restored? I also considered restoring a nandroid backup of my old, working XXJVH.
Which option should I do? Does nandroid backup restore my APN settings, or are they stored elsewhere?
Also, can the APN settings reappear after flashing Slim ICS or some another rom?
