How to fix ( this iphone is currently linked to an apple id) i dont remember my previous apple id

Hi, Or you must to recover your Apple ID or call Apple. There is no way to bypass activation. http://support.apple.com/kb/ht5787 https://iforgot.apple.com/appleid Regards.

You can’t ring Apple and state your case

You don’t. You will have to produce the password—you can get help with password reminders from Apple. If not, you can produce the original receipt. Outside of that, there are a zillion shady companies out there that will take your money to help you launder a stolen phone. There is no well established long lasting solution–at any time you can lose the activation unlock–if you are able to get one–when Apple updates the iOS. This really is a dead end.
