Hi I'm new on here, so bear with me on basic terms.. I got a second hand iPhone 4s that has been erased i think, as showing the language selction, etc.. Problem is that it is saying it needs the iCloud password of the previous owner. Unfortunately, i don't have contact with them. I'm told this is because they turned on Find My Phone and it needs removing off their account. What are my options please? Someone said Jailbreak - what is this? Sombody else said to use a bypass tool? And from my preivous IT background, i wondered if i can swap the motherboard, which presumably would swap the ROM/RAM? By the way, i do have another iPhone at my disposal to take the motherboard from if necessary (everything else on it is useless - on/off button, speaker, screen, all broken) Thanks, Andy.
