A couple of questions regarding iphone 3gs...
I am getting my friends iphone 3gs, I need to unlock it to use on TMobile. I just found out today by the store that was going to unlock it for me, that they are unable to unlock it since software was updated to OS 5.
My question is can I downgrade the OS back to OS 4 and if so, how? Please include a link if you have one.
Other question would be if anyone has indeed unlocked an OS 5? I am near Portland Oregon, any locations you can recommend I get in touch with.
Thanks in advance, any help you can give me would be greatly appreciated.
