Are you with o2 or know someone who is?
where can I find this unlock app please?
I think I found the fault to these handsets. After you unlock the device via o2, when you do a factory reset it prompts you to re-enter the 16 digit unlatching code again.
Yep thanks mate just found it and realised that it was back in stock so reposted it and got another 2 (y)
