Hello all, I am new to the block so please bear with me. I recently bought a used iPhone 4 and am beginning to lose the will to live. I have contacted the previous owner who has been very helpful in giving me the passcode to reset things on the phone. I have just received the instructions from the former network provider T-Mobile as to unlocking the phone, but am getting nowhere. I get warning signs popping up, error codes on iTunes and a panel on the phone asking me if I trust my computer. When I click yes it clearly doesn't trust me as the panel pops up again and again. I now understand I need the passcode for iCloud, or at the least I need the former owner to cancel his iCloud account. Can anyone shed any light on these issues please? I am running iTunes 9 on a 2 x 2.66 Ghz Intel Zeon Mac Pro with Mac OSX 10.4.11. It's an ageing Mac but I don't really see how the age of my Mac is an issue. It's a phone after all, that I am trying to connect with, so it must be something to do with the phone!!!
