As the title states, there's no cases for the Lumia 720 where I live. Is it possible to use a 820 case since its almost the same dimensions? Don't wana keep my phone naked until my online shipment gets here.
What case are you talking of?
I see truckload of soft gel and hard cases on ebay already for a few bucks.
If you don't have ebay, go for a generic pouch.
I really don't think the 820 case will go on a 720 because the 720 is a slim chick, its like wearing an XL size underpant when your real size is L or M.
