As far as I know, maps come from the google apps package which is not customised by Samsung (it gets updated from the market). Is that not right? Also it looks very different from the version I have now, so it's strange in general. I've never seen rounded corners on a text field.

(see this for example: http://www.gadgetnutz.com/wp-content/uploads/2011/09/map.jpg - not similar to what's in the posted gallery)
