Hi I have an Iphone 3gs that my mom bought in thailand. My problem is that it is in restore mode. I don't even know why it happend but it did. The seller told my mom that it was factory unlocked but I don't know if I can trust that. iTunes wants to restore to factory settings and upgrade it to the latest version, it there any way to restore it to 3.1.2 or even erlier versions or is my only option to upgrade it and hope the seller told her the truth? Edit: I know that you can't downgrade an iPhone that is upgraded to 3.1.3 but mine haven't been upgraded yet so maybe there's a way to restore to something that's not the latest version?
