    I need an iPhone developer to create a simple iPhone app for me that does the following:When the application starts for the first time, it takes the phone number from the mobile device settings, shows it to the user to confirm and then communicates to a server to sign up the device. Server sends an SMS with a 6-digits random code to that mobile number (I will supply server side). On the iPhone app side, following user clicking "Sign up", the application will wait for an SMS to be received, read the 6-digits random code (or let user type it in). It will send that code to the server and show a message to user depending on server"s response saying whether signup was successful or not. That"s it. Simple as that. NOTE that I require the app to support all possible iOS versions and devices.Also, communication from there onwards (following signup / sign in) needs to be secured/verified, so I need the app to maintain whatever cookie/session id/device id mechanism required so that it will be dispatched with each subsequent requests made to server and identify each client securely. I am not sure what"s the best (or common) approach to use, so I request each bidder to suggest his approach to that in a sentence or two. Just let me know what would you suggest to use to identify each client later on and be 100% secured.BIDDERS - PLEASE BID ONLY WITH AN ANSWER TO QUESTION ABOVE !

    I would like to have two flashcard programs for studying simple English words. The target user is a low level student of English. The application should be similar to "quizlet", where one side has a picture, supplied by me, and the other side of the flashcard has the English word. If there could be a concentration game, again, similar to quizlet, that would be good. The number of flashcards would be around 200 flashcards for each program.
