How can I import / export contacts as VCF in Sony Xperia Tipo Dual I'm using a Sony Xperia Tipo Dual with ICS. I need to backup my contacts with or without linked contacts.

Does anyone know the exact procedure to export contacts in VCF format; either directly to PC using PC companion or to SD Card using any third party free application?

In addition to that, I want to know if it would be possible to add / update contacts on the mobile through the Sony PC companion?
I am guessing that you are running Sony's TimeScape Interface. (As you not mentioned anything explicitly) So here are steps:

To back up contacts using a memory card:


From the Home screen, tap the Application screens icon.
Find and tap Contacts.
Press the Menu key, then tap Back up contacts > Memory card > OK.


Tested on Xperia Neo, Xperia Neo V, Xperia Ray running 2.3.4 Gingerbread to 4.0.4 ICS with Sony's TimeScape UI. Should work on Tipo as well.
