We have a list of 50,000+ numbers that we need to query Apples servers to detect and extract the valid iMessage users, then be able to broadcast our message to the valid users. To detect valid or invalid iMessage users the program should query Apple servers directly using the applepushserviced via a man in the middle proxy type of method. The server will output in Json format a flag for reach query: 1 for valid and 0 for invalid. The program will be able to output in text format all the valid entires. The program will not use the iMessages program but instead use the applepushserviced to go directly to Apples servers. We should be able to scan at a rate of 10 per second. The second part of the application will allow us to select a text file containing 50,000+ validated iMessage users (that were outputted by the scanning portion of the app described above) and will then allow us to send directly to them, again without using the iMessage app but via the Apple Push Service Protocol at a delay of 17ms between messages. The app must have features including crash recovery so that we don't have to start over from scanning or sending in the event of an app crash. It should also support spintax such as Hi||Hello|Hello there|Good Morning...etc and should include basic stats such as how many have been sent, how many remaining...etc. The app should also allow us to use a push certificate from a jailbroken device and allow it to connect a non-jailbroken device to Apple's servers. This allows us to authenticate a handshake with [login to view URL] as this will allow us to connect a non jailbroken device to apple servers as a jailbroke device. Successful completion of this app would be when we run a test scan of 10,000 numbers with a few hidden known valid iMessage users inserted to ensure they are properly detected as valid also those same hidden valid iMessage users should receive the iMessage after a iMessage blast to a list of 10,000+ valid iMessage users. Bonus Feature: We will be willing to pay extra if you are able to integrate a feature to allow us to set the sender ID to another valid iMessage user than the actual person sending the iMessage.
