I need to export my contacts to a VCF (vCard) file so I can import them into some older mobile phones (basic phones and early Android models). I have noticed that there are different vCard versions available, like vCard 2.1, 3.0, and 4.0, and I am not sure which one works best for legacy devices. My main concern is maximum compatibility rather than advanced features. I do not want contacts to get skipped, show incorrect fields, or fail to import altogether. Which VCF/vCard version is considered optimal for older mobile phone compatibility, and why?
