I am in Singapore and just got a refurbished iPhone since my old one was under warranty. The old one had Cydia, 06.15 iPad firmware, etc. in order to unlock it for local carriers. The refurbished one they gave me is factory unlocked (under local law maybe?). My question is: if I restore the new phone through iTunes, what exactly will be restored? Just apps or will it go to 06.15 instead of 05.15.04?
