i just got another curve from a seller locally and in options-security, and where you can either have the options of enabled or disabled, it shows enabled with a red padlock next to it and wouldnt let me disable having a password on. so i updated the software to OS 4.5 thinking that would restore the factory settings and allow me to disable the password, but its still on there.. is there any way i can get it to be able to have the password disabled?
