Hi, all! I'm trying to create a web service which which can people help to improve vocabulary http://wordsteps.com. This is a web 2.0 project and have some interesting on-line exercises. Now we are programming a mobile client which can synchronize with web service and download dictionaries. People can use mobile exercises to learn new word on the bus stop, in metro etc. The quesion is what platform should we choose first? iPhone is very popular, but in Russia it's not so popular, as Nokia phones. And Android may become one of the most popular mobile OS soon. Please, advice what platform to choose first?
