If your a Vera fan, this case for the 5.0 was made in four colors. The linked is Camellia, Island blooms, Elle Blue, and Rosy Posies. Sometimes it's helps to search by color and look for the photo as some people don't know the style. There was also a cellphone case that was a pulltab in the same colors which fits the 4.2 perfectly. Can search for iphone case. Here's the clip phone case for the 4.2. Also the new crossbody phone case should fit either of the Samsungs.
