Hi,  I realise this is an old post and wondering if anyone is still out there? I have an old Nokia N8 which was tied to O2. I asked O2 to send me an unlatching code, which they did. Turns out this was for a different IMEI number so the phone is now blocked. O2 apologised and offered to send me a new handset (soon realised they’re not still in production, so refunded me £72 instead) I really wanted to reinstate this phone though so wondered if, 8 years later, there is a way to unblock this N8 in the UK?
