Why wont my iphone 3gs go into recovery mode
So I have this old Iphone 3Gs and I got it at an estate sale the person said that it was unlocked but it was not. I have tried everything but it wont go into recovery mode I have searched online for ways to just factory reset it but I guess there is no way to do that either. I just want to have a working phone so I can text my friends and stuff like that I mean I have other phones... But I am quite fond of the older models could someone please help me?
