Someone recommended to me a spreadsheet app called Mariner Calc. The app store only shows an iPad version, though the person who recommended it most definitely has it on their 3G. I went to the author's site and they advertise the iPhone version, even supplying a link to the app store. Clicking that link gives this error: "The item you've requested is not currently available in the US store." I emailed their support last week but haven't gotten a response. Anyone know anything about this?
