I bought recently a z1 compact from ebay and from my unknowledge that guy told me that the phone is locked on o2, but not hardly locked. I accessed that service menu where you can find that your attempts to unlock it by code but is says that i have 0 attempts left. My question is.... Can i do something with this phone to get it unlocked somehow? I tried to go to o2 stores and to call at a sony service center but with no luck. They need the owner's agreement. Thank you!
